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. Its exceptional hardness, second only to diamond and cubic boron nitride, coupled with its high temperature resistance, acid-alkali corrosion resistance, high strength, chemical stability, and lightweight, make it an ideal material across various industries.
Black silicon carbide is produced by smelting quartz sand, petroleum coke (or coal coke), wood chips, and other raw materials in a resistance furnace.
Tabular alumina is a pure sintered alumina, thoroughly calcined without the addition of any additives such as MgO or B2O3. It boasts a coarse, well-developed α-Al2O3 crystal structure, with an Al2O3 content exceeding 99%.
