During the smelting and crushing process of silicon carbide, it is inevitable to produce graphite electrode residues, raw material residues, free carbon, free silicon and other impurities. Therefore, these impurities need to be removed in the subsequent process.
There are several methods to remove impurities from Silicon carbide powder:
SiC ceramic seal ring is a functional ceramic product made of silicon carbide material. It has excellent wear resistance, high temperature resistance, and resistance to chemical oxidation and corrosion. SiC ceramic seal rings work well in aerospace, power equipment, semiconductor equipment, pharmaceutical equipment, petrochemicals, new energy vehicles, precision machinery and other fields. Black silicon carbide 120 grit is a commonly used particle size for manufacturing silicon carbide seals. It gives the excellent performance of silicon carbide seals.
Green SiC powder is usually an auxiliary material added to diamond powder. Its main function is to adjust the hardness of diamond cutting and play a filling role. At the same time, the hardness of green silicon carbide is slightly lower than that of diamond. However, the cost of GC powder is much lower than that of artificial diamond abrasives. Thus, it can acheive cost saving.
In this application, the particle size of green SiC powder are 63um and 50um.
The ready to press SiC powder for pressless SiC ceramics is a low specific gravity silicon carbide powder from spray granulation technology. Here are some tips RTP SiC powder to stock:
The reverse radar of new energy vehicles usually uses aluminum alloy and zinc die-casting parts as the shell. Aluminum die castings are conducive to the realization of vehicle lightweighting. Sandblasting of aluminum die-casting parts can improve their surface roughness. Thus it makes preparation for subsequent chemical surface treatment. 98% Silicon carbide #60 grit(Black color) can perfectly handle this application.
Ordinary grinding materials such as quartz sand, garnet, or corundum abrasive are not hard enough for grinding marble billiard tabletop. Using green silicon carbide 400 grit and 320 grit to grind the tabletop can easily achieve the grinding effect with high surface consistency.
