Language
Black silicon carbide is produced by smelting quartz sand, petroleum coke (or coal coke), wood chips, and other raw materials in a resistance furnace. It appears as a black opaque body with hexagonal crystals and a Mohs hardness of 9.15. Second only to diamond and boron carbide, it possesses brittle and sharp properties with a certain degree of conductivity.

Casting process
Ceramic foundry sand is made from high-quality calcined bauxite, processed through electric fusion, granulation, and screening processes to produce spherical refractory particles.
Glass beads, produced from crushed glass and flat glass materials, are processed into spherical shapes through high-temperature melting.
Boron carbide is produced through high-temperature smelting of boracic acid and carbonaceous materials in electric furnaces. It boasts a theoretical density of 2.52g/cm3, a melting point of 2450°C, and a micro hardness of 4950kgf/mm2.
Bubble alumina is a new type of high-temperature insulation material, consisting of a-Al2O3 microcrystals.
Fused Alumina
Use in many different industries such as abrasives, refractories, sandblasting etc.
