Boron carbide is a black crystal with a metallic luster, commonly known as black diamond. It is a granular or powdered product made primarily from boric acid, with the addition of carbonaceous materials such as petrol coke, through high- temperature melting and pulverization. It possesses properties such as high temperature resistance, acid and alkali corrosion resistance, high strength, good chemical stability, light weight, and neutron absorption.

It possesses properties such as high temperature resistance, acid and alkali corrosion resistance, high strength, good chemical stability, light weight, and neutron absorption. Its Mohs hardness is as high as 9.3 g.5, only after diamond and cubic boron nitride. Its theoretical density is 2.52 g/cm3, melting point is 2450°C, and microhardness is4950 kgf/mm2.
Bulletproof plates in vests, ceramic bulletproof tiles for military aircraft cockpits, and ceramic bulletproof plates for modern armored personnel carriers and tanks.
Control rod sand shut-off bolts for nuclear reactors;boron carbide tiles, plates, or neutron absorbers ( made with high B10 content powder) for radiation protection; or mixed with cement to create nuclear reactor shielding layers.
Spray gun nozzles , water jet cutter nozzles, sealing rings, and ceramic molds.Used in welding rods to enhance the wear resistance of weld surfaces.
Widely used as an antioxidant and filler in magnesia carbon bricks, iron trough castables, and other main materials.
abrasive for water jet cutting, and a finishing material for diamond grinding tools.
