In semiconductor production equipment, high-performance ceramic components are essential. Especially silicon carbide ceramics are important components in key equipment such as etching machines, lithography machines, ion implantation machines, etc. For example, grinding and polishing suction cups, photolithography suction cups, inspection suction cups, etching processes, and motion platforms all have the presence of silicon carbide ceramics. These silicon carbide ceramic components have good structural stability, thermal stability, wear resistance, corrosion resistance, and high dimensional accuracy. Silicon carbide powder, as the main raw material for producing silicon carbide ceramics, must also have good and stable properties. Among them, black SiC powder 800# for porous silicon carbide ceramic suction cups is a typical application.
