Boostec ® silicon carbide -SiC- for scientific instrumentation and industrial equipment Mersen Boostec is specialized in the development of innovative products made of sintered silicon carbide. For some appliions, the silicon carbide can receive a CVD (chemical vapor deposition) coating to give a completely non-porous high-purity SiC surface.
Silicon Superjunction devices use the charge balance principle, where equal doping of the n- and p-columns amounts to essentially zero net charge, and can therefore allow rapid depletion for voltage support, even if the n-columns are heavily doped for low
Bullet-proof plates and body armours are made of ceramic,silicon carbide and boron carbide with high strength,high hardness,high compression resistance,smaller density and high modulus of elasticity.Different standard sizes of bulletproof plates can be available
Silicon carbide (SiC), also known as carborundum, is a compound of silicon and carbon with chemical formula SiC. It occurs in nature as the extremely rare mineral moissanite. Silicon carbide powder has been mass-produced since 1893 for use as an abrasive.

Silicon carbide (SiC) ceramic is an ideal material for mechanical seal because of its super hardness, high strength, low friction coefficient, good thermal conductivity, and resistance to friction and wear. However, due to relatively high resistivity of SiC ceramic, the triboelectric charge caused by rubbing of mechanical seal end-faces could not be released. It is terrible that the
