SILICON
CARBIDE
ABRASIVE
Silicon Carbide is one of the hardest available abrasives blasting applications. Silicon carbide is capable of high-efficiency profiling with the benefits of high friability and inert chemical properties.
Silicon carbide is a man-made material manufactured by the Acheson furnace technique. Silicon carbide is an extremely hard material (Mohs hardness 9.25), is chemically inert and does not melt. Silicon Carbide has a high thermal conductivity, a low coefficient of thermal expansion, is thermal shock and abrasion resistant and has strength at high temperatures. Silicon carbide’s varied properties make it an effective material in many different applications.
