Boron carbide bulletproof ceramics

Boron carbide bulletproof ceramics
Carbonized bridges are the superhard materials of bridges and cubic boron nitride among the currently known materials. Among these ceramics, they have the highest ceiling and the lowest density. The stairs are 2.52g/cm3, which is 1/3 of steel; the elastic modulus High, low thermal expansion coefficient and high thermal conductivity. In addition, boron carbide has good chemical stability and is resistant to acid and alkali corrosion. It does not react with acids, alkalis and most inorganic compounds at room temperature; it does not wet or react with most liquid reactive metals. Boron carbide also has a good ability to absorb neutrons, which is not available in other ceramic materials.
