What’s samarium dioxide powder?
Boisbaudler was a pioneer in rare earth elements and discovered one new element from the “praseodymium neonium”, a mineral obtained from the niobium ore. He named it Samarium after the ore.
Samarium is a yellow-colored raw material that is used to make samarium and 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 cobalt magnets don’t require a very high level of purity. The majority of products can be used for their cost. Additionally, simarium oxide powder has been used in ceramic catalysts and ceramic capacitors. Additionally, samarium can also be used to create structural materials or shielding materials. It is therefore possible for the vast amount of nuclear energy that has been generated from nuclear fission and be safely utilized.
Preparation for samarium-oxide catalyst
The one-step procedure for creating a steel sulfide/samarium oxygenoxide composite photocatalyst
This invention reveals a method of making an indium sulfuride/samarium oxygenoxide composite photocatalyst. First, dissolve In(NO3)3*4.5H20 in deionized waters to make a solution. Next, weigh Sm(NO3)*3.6H20 and add it to the mix solution A. Stir the mixture to create the B. Finally, subject the B to 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 to the mixed solution A. Stir the mixture B and finally, dry the mix. It is easy to manage and heat uniformly. There are no miscellaneous phase, high utilization rates, low cost raw materials, and easy availability of the product. These factors effectively increase the photocatalytic activities and stability. They can also be used for degrading organic wastewater pollution.
1. One-step process for creating indium sulfuride/samariumoxyhydroxide composite photoscatalyst. This method is distinguished by the following:
Step 1: In(NO3)3*4.5H20 is first dissolved in deionized tap water. Then weigh the thioacetamide according to the element mole ratio nIn.ns=1; and then stir to produce mixed solution A.
Step 2: Add Sm(NO3)3*6H20 to the mixed solutions A according the molar ratio (nIn:nsm=1;(0.40.7) and mix to get the mixed remedy B:
Step 3: Mixture B was put through a homogeneous heat treatment. Once the reaction had completed, the product could be removed and centrifugally washed in deionized and absolute water several times. Finally, it was 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.
