The Chemical Formula of Silicon Carbide, which is also known carborundum, is SiC. It is produced by the carbothermal reduction of silica to form an ultra-hard covalently bonded material. It is extremely rare in nature but can be found in the mineral moissanite, which was first discovered in Arizona in 1893.
This includes both the industry-unique beta-silicon carbide products (synthesized domestically by Superior Graphite), and alpha-silicon carbide and boron carbide powders. We produce these materials using state-of-the-art ceramic powder sizing capabilities, enabling controlled particle size distributions, and custom blends of powders, which supports dis-similar material, bi-modal, and other
The interior of the fiber element was composed of sintered β-silicon carbide crystal without an obvious second phase at the grain boundary and triple points. This material showed high strength (over 600 megapascals in longitudinal direction), fibrous fracture behavior, excellent high-temperature properties (up to 1600°C in air), and high thermal conductivity (even at temperatures over 1000°C).
