Description of Zinc Sulfide :

Zinc sulfide chemical formula is ZnS, and the molecular weight is 134.72. It is formed by interacting with zinc ions (Zn2+) and sulfur ions (S2-) through ionic bonds. The zinc ion is located in the center of a regular tetrahedron formed by four sulfur ions in the crystal structure. In contrast, the sulfur ion is located in the center of a tetrahedron. This structure can be described as a face-centered cubic crystal system in which zinc and sulfur ions occupy the vertex and face-centered positions of the lattice, respectively.

Zinc Sulfide is an insoluble white solid that is insoluble in water but is soluble in bases and acids. Its density is 3.98 grams per cubic centimeter with a melting temperature of 1350 degrees C and an optimum boiling temperature of 1650 degrees C. Zinc sulfide has high hardness and good optical transparency, and its light transmission range is 200-400nm. The chemical properties of zinc sulfide are relatively stable, but it can also react under certain conditions. For example, in the presence of an oxidizing agent, zinc sulfide can be oxidized to form zinc sulfate. In an alkaline environment, zinc sulfide can react with hydroxide ions to form zinc hydroxide.

Application of Zinc Sulfide :

For example, zinc sulfide can be used in optical fiber communications to manufacture optical fiber preforms. In addition, zinc sulfide can also be used to manufacture optical devices such as optical Windows and optical lenses.

Production Method of Zinc Sulfide :

1. chemical precipitation method

Chemical precipitation is a common method for preparing zinc sulfide. By mixing zinc salt and sulfur salt in a solution, precipitation, filtration, and drying of zinc sulfide powder were obtained:

Preparation solution: Dissolve an appropriate amount of zinc and sulfur salt in water to make a solution.

Precipitation reaction: The above solution is heated under stirring conditions, and an appropriate amount of precipitating agent is added to precipitate zinc ions and sulfur ions to generate zinc sulfide precipitation.

Filtration: The reaction solution is filtered to obtain a filtrate containing zinc sulfide precipitation.

Washing: The filtered zinc sulfide precipitation is washed with alcohol to remove residual impurities and solvents.

Drying: The zinc sulfide, after washing, is precipitated and dried to obtain zinc sulfide powder.

The advantages of chemical precipitation are simple to process, low cost, and high product purity. However, this method requires many precipitating agents and detergents, and the generated waste liquid must be further treated before discharge, which has a certain environmental pollution.

2. high-temperature solid phase synthesis method

High-temperature solid phase synthesis is a traditional method for preparing zinc sulfide. Zinc sulfide powder was obtained by a solid reaction of zinc and sulfur oxides or elements at high temperatures:

Ingredients: The appropriate amount of zinc oxide, carbon powder, and sulfur powder is mixed in a certain proportion to make raw materials.

Pretreatment: The raw materials are pretreated at high temperatures so that each component fully reacts to generate zinc and sulfur vapor.

What property does zinc sulfide have?

Zinc sulfide This inorganic compound has a chemical composition of ZnS. It appears as a powder that is white, off-white or yellow. Zinc Sulfide is stable when in dry air. When in humid air over a period of time or with moisture, it gradually oxidizes to zinc sulfate. It is insoluble when mixed with water and soluble when mixed with dilute inorganic acids.
Zinc Sulfide is usually obtained through the reaction of hydrogen sulfide with zinc salt solutions. When a small quantity of Cu,Mn,Ag is added to the crystal ZnS as an activater, it will emit different colors after illumination.

What are the applications of zinc sulfide?

The zinc sulfide compound semiconductors are important because they have outstanding physical characteristics, including a large band gap, high refraction index, and high transmittance of visible light. They also offer great potential for optics, electronic, and optoelectronic applications.

Zinc Sulfide exhibits excellent electroluminescence and fluorescence effects. Nano-zinc has a unique effect. It has excellent properties in the areas of magnetism (electricity), optics (optics), mechanics, and catalysis. It is for this reason that research into nano-zinc-sulfide caused a lot of controversy. In 1994 Bhargava reported on the surface passivation properties of nano ZnS:Mn-phosphor, which not only had an external quantum efficiencies of up to 18% at high temperatures but also a fluorescence life of five orders of magnitude shorter. The performance of ZnS has improved dramatically, opening up new possibilities for its use in materials.

What is Zincsulfide ZnS Pulp? Zincsulfide An inorganic compound with chemical formula ZnS. Zinc Sulfide is a powder that can range in color from white to pale yellow to light-yellow. It turns darker when it is exposed to light. It is stable in dry conditions, but it slowly oxidizes into zinc sulfate when exposed to moisture or in moist air. Soluble in dilute inorganic acid, soluble in alkali, insoluble in water.

Zinc Sulfide SnS Structure
ZnS can be found in two main types of crystals. The prominent example of the polycrystalline duality is typically one that contains ZnS. Each form has a tetrahedral coordination geometry. The stable cubic form, also known as sphalerite, is also known. The mineral wurtzite is the hexagonal form. However, it can also be synthesized synthetically. The temperature at which sphalerite becomes wurtzite is 1020°C. The tetragonal form of sphalerite is also known as a rare mineral called lithium manganese. It has the formula (Zn Hg) S.

For what is Zinc Sulfide ZinS used?
Zinc sulfuride is used mainly in paint and plastics for chemical production. Zinc sulfide has become an important pigment in paint due to its white opaqueness and insolubleness in water, organic solvents and weak acid and weak base. Zinc sulfuride is the second most important pigment in America after titanium dioxide. However, it continues to play a significant role in European industry.
Zinc sulfide has a melting point of 1650. The Mohs toughness of 98% of the commercial-grade zinc is 3.0. The refractive index, 2.37. Due to its high wear resistance and refractive index, zinc sulfide is a good choice for equipment, wax paper and metal plates with thin layers.
Zinc sulfuride is easy and simple to disperse. It is a neutral-white metal with excellent optical properties. It is commonly used as a component in thermosetting plastics and thermoplastic plastics.

Luminescent Material
Zinc sulfuride is a mixture of zinc sulfide and a few parts per million of a suitable activator. This produces strong phosphorescence, as described by Nikola Tesla, in 1893. It is currently used for many purposes, including X-ray screens, cathoderay tubes, and products that glow in darkness. The result is bright blue when silver is used as an activater. It has a maximum size limit of 450 nanometers. Manganese is used to produce an orange-red color with a maximum size of 590 nanometers. Copper glows brightly for long periods of time and gives off a familiar green glow. In electroluminescent panels, copper-doped zinc Sulfide (" ZnS + Cu ") can also be used. It also displays phosphorescence from impurities that are exposed to blue and ultraviolet light.

Optical material
Zinc sulfuride can also serve as an infrared optical medium, transmitting at just 12 microns between visible wavelengths. You can either use it flat as an optical window, or mold it into a lens. It is manufactured by synthesizing hydrogen sulfur gas and zinc vapour on a microchip. This product is FLIR grade (forward looking infrared), which means that zinc sulfide can be found in an opaque milky yellow color. Cleartran is a transparent material that can be transformed under high isostatic pressure (HIPed). IRTRAN-2 was the name of the early commercial form, but it has since been dropped.

Pigment
Zinc sulfide can be called Sachtolith. Zinc sulfide can form lithopone when it is combined with barium-sulfate.

Catalyst
Fine ZnS is a high-efficiency photocatalyst which produces hydrogen gas under light. Sulfur vacancies can be used in the synthesis and transformation of zinc sulfide. This makes the ZnS gradually brown and increases light absorption.

Semiconductor characteristic
Both wurtzite, and sphalerite have a wide band-gap. These are IIVI semiconductors typical that have structures similar to other semiconductors such as gallium arsenide. The band gap between the hexagonal and cubic forms of ZnS is approximately 3.91 EV at 300 Kelvin. ZnS is available in both n-type and P-type forms.

Introduction to Zinc Sulfide ZnS Pulver Zinc sulfide An inorganic compound that has the chemical composition ZnS. It is a powder with a yellowish color that darkens upon exposure to sunlight. It is stable when dry, but it will slowly oxidize to zinc sulfurate over time if left in humid conditions. It is most often formed by the reaction of hydrogen sulfide in zinc salt solution. Zinc sulfuride is very fluorescent and has excellent electroluminescence functions. Particularly: nano zinc sulfide It exhibits a unique and powerful photoelectric effect and has many great properties in the areas of electricity, magnetism mechanics, catalysis, and optics.

Zinc Sulfide ZnS Pulver: Physicochemical Characteristics
The covalent chemical bond between Zn sulfide and S of zinc is more common. Three types of crystal are available: Low-temperature type, which is the sphalerite crystal that is found abundantly in nature, and colorless cubic crystal. The Zn S coordination number is 4 and the relative density is 4.10. At 1020, it will transition to high temperature type. High-temperature types, that is, wurtzite structures, are colorless hexagonal crystals, Zn, and S coordination numbers are 4, the relative densities are 3.98 and the melting point is around 1700. It is a high-temperature zinc sulfide stable structure. The sodium chloride type, which is Zn, S number are 6, has a relative density of 5.21. The aqueous compound ZnS*H2O also exists, which is a white powder having a relative density of 3.98 with a melting point 1049. Zinc sulfuride is insoluble and insoluble with water and dilute acid. It is also insoluble and insoluble when acetic acids are present. However, it can be dissolved in low concentrations in strong acids, such as hydrochloric, which releases hydrogen sulfide. The solubility of zinc sulfide resembles the K1*K2 value for hydrosulphuric Acid, so there is the following equilibrium in dilute acid.
Zn2+H2S=2H+ZnS
It is clear that zinc sulfide can not be precipitated in the acidic zinc sodium solution. When hydrogen sulfide gases is added to zinc salt solution, zinc sulfide precipitation may be possible, but it is not complete. Ammonium sulfide can be used as a precipitant to precipitate zinc ions from zinc salt solution. The alkaline nature of ammonium solution allows for the reduction in the acidity. This method is used to separate air in industry. When exposed to light, white zinc sulfide turns dark and can easily be oxidized to zinc oxide in air. Zinc sulfuride can be used in white paint pigments by itself or with zinc oxide. Pure zinc sulfide does not emit light. As activators, zinc sulfide crystals can emit different colors after light irradiation. Zinc sulfide has many uses in leather, dye, rubber and enamel as well as other industries.
