Calix Ceramic Solutions creates sintered silicon carbide and other advanced ceramic materials that are perfect for various appliions, including chemicals and alternative energy processes. Learn how our ceramic materials are resistant to wear, abrasion, crushing, chemicals, and more.
Silicon Carbide is a non oxide ceramic and is used in a wide range of products that must perform in thermally (high heat and heat shock) and mechanically demanding appliions. It is employed in both abrasives and wear resistant parts for its hardness; in refractories and ceramics for its resistance to heat and low thermal expansion; and in electronics for its thermal conductivity and other

Brevier Technical Ceramics - Keramverband
The mechanical properties of boron carbide ceramics are similar to those of silicon carbide, with the exception of comparatively high wear resistance. The coination of very low density (2.51 g/cm3), high mechanical strength and high elastic modulus makes this type of ceramic particularly attractive in the field of ballistic protection.
Silicon carbide — Wikipedia Republished // WIKI 2
Because natural moissanite is extremely scarce, most silicon carbide is synthetic. Silicon carbide is used as an abrasive, as well as a semiconductor and diamond simulant of gem quality. The simplest process to manufacture silicon carbide is to coine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1,600 C (2,910 F) and 2,500 C (4,530 F).
