Titanium diboride powder The hexagonal structure of the crystals (AlB2) is grayish-black. The melting temperature of titanium diboride (2980degC) is high, and it also has a very hard surface. It is stable to HCl, HF and anti-oxidation temperatures. Titanium Diboride is used primarily to prepare composite ceramics. Due to its ability to resist corrosion, titanium diboride may be used for the production of electrolytic cell electrodes and molten metallic crucibles.

The Preparation Of Titanium Diboride

There are many methods that can be used to prepare titanium diboride. These include the carbothermic method of reduction, the self-propagating method at high temperature, the mechanochemical method of reaction, and ball milling.
1.Carbothermal Reduction Method
The quality of the titanium diboride powder synthesized depends on the powder purity. This is achieved by using titanium and boron oxids as raw materials. Carbon black is used as a reducing agent. This process is widely used in industrial production. The powder obtained from this process has large particles and is high in impurities.

Self-propagating High-Temperature Synthesis (SHS)
In general, this method involves pressing a raw material mixture into a solid block. One end of the solid block is then ignited to ignite the chemical reaction. The reaction releases a huge amount of heat, which causes adjacent materials to react. Eventually a combustion waves spreading at speed v forms. As the combustion waves advance, the raw materials are transformed into the finished product. The self-propagating, high-temperature method can be combined with special technical means to produce a dense material of titanium diboride.

3.Mechanochemical reaction (MR)
In this method the reactant powder, which is made of a reactive substance, is placed into a high-energy grinding ball. The powder will be repeatedly deformed under the pressure of the grinding balls. The ball milling medium generates chemical energy through the violent friction. Comparing the two first methods of preparing titanium dioxide, the mechanochemical reactions method has advantages such as low synthesis temperatures, a wide range of raw material sources, and low costs.

The Application of Titanium Diboride

Titanium diboride can be mixed with ceramic polymers and other metals to create new materials that have commercial applications.

1.Titanium boride can serve as an additive for grain refinement or particle strengthening. It can be used to enhance the mechanical and physic properties of materials based on aluminum, copper and titanium-aluminum alloy.

It is possible to combine titanium diboride and non-oxide ceramics, such as silicon carbide, aluminum nitride or boron carbide. Or, it can be combined with oxide ceramic materials, such as alumina.

PTC head-type materials and PTC heating ceramics can be created by mixing titanium diboride powder with high performance resin. They have many advantages, such as safety, energy saving, reliability and easy processing. These include electric irons (and blankets), electric ovens (and air conditioners), and electric blankets. This is a key high-tech to upgrade household appliances like hot-air heaters.

It has excellent electrical conductivity, and is resistant to corrosion caused by molten metallic. It is used for evaporators as well as aluminum electrolytic cells cathodes, electrodes, contact heads, and molten-metal crucibles.

5. By using titanium dioxide as the cathode material for the aluminum electrolytic battery, the cell's power consumption can be reduced and its life extended.

6. Titanium diboride may be used in the manufacture of ceramic tools and molds. It is used for the manufacture of finishing tools, wire drawings dies extrusion dies sandblasting components etc.

Metal borides, among many other compounds, have better performance at high temperatures than do metal carbides. As an example, titanium diboride (TiB2) The cermet product is more suitable for use in high temperature, high corrosion conditions.
The properties of titanium diboride both as structural and functional materials

1. Structure materials. Due to its high strength, titanium boride can be used for tools, wire drawing films, sandblasting materials, and other hard tooling materials. It can also be added to composite materials.

2. Functional materials. It is a very useful material for functional materials because the resistivity of titanium is similar to pure iron. Titanium boride's electrical properties can be used to create flexible PTC material.

There are many methods to prepare titanium diboride. These include the carbothermal method of reduction, the self-propagating method at high temperatures and synthesis, the mechanochemical method of reaction, and ball milling.

In general, this method involves pressing the raw material mixture into a solid block. One end of the solid block is then ignited to ignite the chemical reaction. The reaction releases a huge amount of heat, which causes adjacent materials to react. Eventually, a combustion-wave spreading at speed v forms. As the combustion wave moves forward, the raw materials are transformed into the finished product. Because of the self purifying effect, the high-temperature synthesis self-propagating process produces a high-purity product. This powder is easily sintered with low energy consumption. With the use of other technical means and special techniques, it is possible to prepare dense titanium diboride directly.

It is important to note that the word "you" means "you". titanium diboride The powder is grayish-black with a hexagonal structure (AlB2). It has a high degree of hardness and a melting temperature of 2980degC. The titanium diboride anti-oxidation temperatures in the air are up to 1000 and it is stable with HCl acid and HF.

Titanium Diboride Powder Properties

Titanium diboride is the most stable of all the compounds containing boron or titanium. It has C32 structure, and valence bonds are used to combine it. It is a hexagonal metalloid. The crystal's structural parameters are: C is 0.3228nm; a is 0.302nm.
The two-dimensional network formed by the boron plane and the titanium plane in the crystal structure alternately forms a covalent bond between B and the other three Bs. An extra electron creates a large p-bond. The graphite like layered structure between boron electrons and Ti outer layers determines TiB2's good conductivity, metallic luster, and hardness.
