silicon carbide micro powder

Silicon Carbide is one type of man-made material for the steel making or casting, the silicon carbide micro powder is refer to one high-tech material, because of the particle size is small general in the mesh size like 320mesh, 700mesh, even can reach 2000mesh, so call it the micro powder silicon carbide.

In order to get this powder, will need the equipment Raymond Mill, it can set specific granularity, so can simply separate our different particle size, but it will mix some other different particle size. Then fine separation of particle size by dry and wet methods, the dry methods is using the difference in airflow wind to divide the particle size, the wet methods is using the difference in water flow to divide the particle size. 

For the general silicon carbide lump or granule, powder, the purity will be 70%, 88% or 90%, but for the silicon carbide micro powder the purity need to be very high, for the green silicon carbide, the purity can reach 99%, and for the black silicon carbide can reach 98.5%. After the particle size separation, there are impurity especially the Fe2O3 will cause big influence for different usage, so it need to add acid to remove the Fe2O3, but it will make the silicon carbide micro powder to be acidic, the standard need the PH of silicon carbide to be 6.5 at least, so will also need the the equipment of acid press deacidification, it is now in the mortar condition, the final step is to dry.

The silicon carbide 88%-90% lumps is generally used in the foundry, and the content below 70% is always used in the steel making as deoxidizer, for the silicon carbide micro powder is generally used into the photovoltaic solar energy as the material of crystal silicon cell cutting, what is more, it can also be used into the special paint.

Anyang Huatuo Metallurgy can not only supply the silicon carbide lump, powder, but also the micro powder, only if you have the interests, welcome for your contact.
