- Boron carbide is mainly used in carbon-containing refractories to have an anti-oxidation effect. It can densify the product and prevent the oxidation of carbon in carbon-containing refractories. At the same time, with the columnar crystals generated and is distributed in the refractory In the crystals and gaps, the porosity is reduced, the medium temperature strength is improved, and the volume of the generated crystals expands, which can heal volume shrinkage and reduce cracks.
- Boron carbide is one of the hardest artificial abrasives, with a Mohs hardness of 9.5, a micro hardness of 43149.26—52955.95n/mm2, a specific gravity of 2.52g/cm3, and a melting point of about 2450°C. It does not react with acid and alkali solutions. Boron carbide also has the characteristics of high chemical potential, neutron absorption, non-magnetic, semiconductor conductive, and high grinding efficiency.
- Boron carbide is suitable for the grinding, grinding, drilling, polishing of various hard alloys, knives, cutting tools, molds, gems and other precision components. It is also refractory materials, high temperature resistant materials, wear-resistant electrodes, and production of metal borides and boron alloys. The main raw materials for manufacturing engineering ceramics, boron steel, etc., were initially applied in the military field and aerospace technology, and are currently irreplaceable materials in the nuclear industry.
