What is Boron Carbide?
Borne carbide is produced by high-temperature smelting of boron additives and carbon materials in an electric furnace.
The theoretical density of boron carbide is 2.52 g/cm³; its melting point is 2450℃; and its microhardness is 4950 kgf/mm².
The hardness of boron carbide is only lower than that of diamond and cubic B4C.
Borne carbide possesses characteristics such as high temperature resistance, acid and alkali resistance, high strength, good chemical stability, and low specific gravity. Therefore, boron carbide (B4C) is widely used in many new materials fields.

Application of B4C in national defense industry
B4C can be used to produce bulletproof materials, such as bulletproof plate in bulletproof vests, ceramic bulletproof tile in military airplane pilot cabin and bulletproof plate in modern armored personnel vehicle and tank. It can also be used to produce the nozzles of gun and artillery in munitions industry.
For Nuclear Industry
B4C can be prepared into controlling bars, adjusting bars, accident bars, safety bars, screen bars, radiation resistant B4C tilts, plate, or neutron absorber(prepared with high B10 content powders),and radiation resistant layer for atomic reactor together with cement which is the most important functional component only next to reactor fuel.
For Refractories Industry
B4C can be used as anti-oxidation agent for low carbon magnesia carbon brocks and castable. It can be applied in key positions which suffer from serious erosion and high temperature, such as ladle, taphole(nozzle),sliding plate and stopper.
For Other Engineering Ceramic Materials
B4C can be prepared into nozzles for sand spraying machine and high pressure water cutter, ring seal, mould for ceramics etc
For Normal Industry Fields
B4C is used to prepare: high grade wear-resistant welding rods to strength the wear resistance of welding face; grinding and polishing materials, water cutting abrasives and polishing materials for diamond abrasives tools; polishing and grinding of jewels.
Application of B4C on Electrical Property
B4C-graphite thermocouple is composed of graphite pipe, B4C bar and BN Lining.In inert gases and vacuum, its service temperature is 2200℃,the linear relation of electric potential difference and temperature is good
Application of B4C as Chemical Material
After being activated nu halogens, B4C powder can be used as boronation agent of steel and other alloys for boronizing on the steel surface, forming a thin iron boride layer, increasing the strength and wear resistance of the materials.
