Silicon Carbide (SiC) has emerged as an essential technological material. It’s utilized for use in abrasives, technical ceramics and refractories – as well as semiconductor manufacturing. Produced by heating silica sand mixed with carbon in the form of petroleum coke at high temperatures in huge open “Acheson” furnaces, SiC is then produced in both Green […]

Silicon carbide is an abrasive material commonly found in grinding wheels, sanding belts and blast media. As an inorganic chemical compound it competes with diamond and boron carbide in terms of hardness. Black silicon carbide (Carborundum) is one of the most commonly used abrasives, featuring hard and angular grains that make for effective processing of

Silicon carbide (SiC) possesses an unusual crystal structure. It contains four Si and four C atoms in an ordered coordination tetrahedral arrangement with layers stacked into polytypes forming its primary coordination tetrahedron. Electrically, silicon carbide has the ability to withstand voltages five-ten times higher than silicon. This makes it an excellent material choice for power

Technology advances are once-in-a-generation events for semiconductor businesses, and those that accept them stand to reap enormous profits. Cree, now Wolfspeed, stands to benefit from the trend towards silicon carbide power devices. Their innovations in device design and production allow them to manufacture smaller chips with equal power ratings on each wafer – thus expanding

Okamoto et al. measured the conductivity of silicon carbide at various temperatures and found that small amounts of Si additive did not increase conductivity by two to three orders of magnitude, but exceeding 5 mol% caused conductivity levels to soar by up to three orders of magnitude. Silicon carbide is a semiconductor material, capable of
