Hard black with glossy crystals. Harder than industrial diamond, but higher than silicon carbide. Fragility is low compared to most pottery. With a large thermal energy neutron capture cross section. Strong chemical resistance. Not subject to hot hydrogen fluoride and nitric acid erosion. Dissolved in the molten alkali, do not dissolve in water and acid. The relative density (d204) 2.508 ~ 2.512. The temperature of 2350 ° C. The boiling point of 3500 ° C.
Properties of boron carbide: Hard black and shiny crystals. Harder than industrial diamond, but higher than silicon carbide. Fragility is low compared to most pottery. With a large thermal energy neutron capture cross section. Strong chemical resistance. Not subject to hot hydrogen fluoride and nitric acid erosion. Dissolved in the molten alkali, do not dissolve in water and acid. The relative density (d204) 2.508 ~ 2.512. The temperature of 2350 ° C. The boiling point of 3500 ° C.
The use of boron carbide: because of low density, high strength, high temperature stability and chemical stability characteristics. In the wear-resistant materials, ceramic reinforced phase, especially in light armor, reactor neutron absorber and other aspects of use. In addition, compared with diamond and cubic boron nitride, boron carbide is easy to manufacture, low cost, and thus more widely used, in some places can be expensive diamond, common in grinding, grinding, drilling and other applications.
