High purity Silicon carbide powder has the characteristics of strong oxidation resistance, good high-temperature chemical stability, and corrosion resistance. It is an ideal choice as a silicon carbide ceramic membrane material is made by high-temperature sintering. It can be used as a three-way catalyst for automobiles and a DFP ceramic membrane to filter exhaust gas and diesel particles.
Automobile three-way catalysts are generally used to treat automobile exhaust, oxidize CO, HC, and NOX. It can reduce harmful gases to harmless carbon dioxide, nitrogen, and water vapor. And DPF (Diesel Particulate Filter) can reduce the particulate matter in diesel engine exhaust and play a role in filtering pollutants. The silicon carbide ceramic membrane made of high-purity silicon carbide material has the following characteristics:
It has good chemical stability and can prevent strong acid, strong alkali, and strong corrosion.
The particle size of the silicon carbide powder is concentrated, and the produced silicon carbide ceramic film has a uniform texture.
Good thermal stability and excellent thermal shock resistance.
Good wear resistance, prolong the service life of the ceramic membrane.
The high purity silicon carbide powder of 99% SiC content can help the silicon carbide membrane to achieve good performance.
The commonly used silicon carbide powder has a particle size of 400 mesh, 600 mesh, 800 mesh, and 1200 mesh. Green silicon carbide powder and black silicon carbide powder both works for different users.
