What's samarium dioxide powder?
Boisbaudler found a rare earth element within the "praseodymium neonium", a mineral obtained from the niobium ore. They named it samarium, after this ore.
Samarium is light-colored and the main ingredient in samarium/cobalt magnets. Industrially, Samarium cobalt magnets have been the first to use rare-earth magnetic materials. Permanent magnets can be classified into two groups: SmCo5 or Sm2Co17. SmCo5 series, and Sm2Co17 series were developed in the mid- and late 1970s. Samarium oxide is not required to be very pure for use in cobalt magnets. The majority of products can be used for their cost. Another use for
Samarium oxide powder in ceramic capacitors is as a catalyst. Additionally, samarium can also be used to create structural materials or shielding materials. It is also able to control nuclear reactors and allow for the safe use of nuclear fission's enormous amounts of energy.
Preparation for samarium dioxide catalyst
An easy method to prepare steel sulfide/samarium-oxyhydroxide composite photocatalyst
This invention reveals a method of making an indium sulfuride/samarium oxygenoxide composite photocatalyst. First, dissolve the In(NO3)34.5H20 into deionized and heat the mixture to make a solution. Second, weigh Sm(NO3)3.6H20 and add it to the mix solution A. Third, stir the mixed reaction B to achieve homogeneous hydrothermal reactions. Once the reaction has completed, take the product out and wash it several times in deionized water. Then, add the element molar ratio nIn:ns=1:3. Stir to get the mixed solution A. Next, weigh Sm(NO3)3.6H20 and stir into the mix. It is easy to manage and heat uniformly. There are no miscellaneous phase, high utilization rates, and low cost raw materials. The product can also be easily obtained, which improves photocatalytic activities and stability.
1. One-step process for creating indium sulfuride/samariumoxyhydroxide composite photoscatalyst. This method is distinguished by the following:
1st Step: First dissolve In(NO3)34.5H20 (deionized) water to prepare a solution. Then weigh thioacetamide according to the element mole ratio nIn.ns=1; and then stir to produce mixed solution A.
Second Step: Weighing Sm(NO3)36H20. Add to mixed solution A according the molar ratio (nIn:nsm=1;(0.40.7) and mix well to get the mixed solutions B.
Step 3: Mixture B was put through a homogeneous heat treatment. Once the reaction had completed, the product could be removed and centrifugally rinsed with absolute alcohol and deionized waters several times before being dried to produce the In2S3/SmOOH composite photographcatalyst.
2. A one-step method for preparing an indium sulfide/samarium oxyhydroxide composite photocatalyst according to claim 1, characterized in that in step 1, 1.145gIn(NO3)3*4.5H20 is added per 30mL of deionized water.
3. Method for creating an indium-sulfide/samarium oxide composite photocatalyst in one step according to claim 1. This method is distinguished in that step 2 and 3 require 60 minutes of stirring.
4. Method for creating a photocatalyst of steel sulfide/samarium oxide composite according to claim 1 in one step. In particular, in step 3 the mixture B is subject to a homogeneous heat treatment. The mix solution B is then transferred to a hydrothermal kettle and placed in a reactor.
5. Method one for the preparation of an indium/samarium photocatalyst composite photocatalyst indium sulfide/samariumoxyhydroxide, as claimed in claim 1, except that step 3 is vacuum drying.
6. One-step procedure for creating an indium sulfide/samarium oxide composite photocatalyst, according to claim 5. The drying temperature at step 3 is 60. The drying time at step 5 is five hours.
