Black diamond or black diamond powder is boron carbide?

4 Comments / News / By SCHX_Admin

Boron carbide, with the chemical formula B₄C, commonly known as black diamond, is a high-performance inorganic superhard ceramic material. It ranks among the top three hardest materials in nature, second only to diamond and cubic boron nitride, with a Mohs hardness of approximately 9.5 and a Vickers hardness exceeding 30 GPa. It appears as black, lustrous crystals, with a grayish-black powder. It is an indispensable special material in industrial and cutting-edge technology fields.

What’s boron carbide B4C? What are boron carbide’s uses?

1 Comment / News / By SCHX_Admin

Boron carbide B4C is produced by high-temperature smelting of boric acid and carbon materials in an electric furnace. Its theoretical density is 2.52 g/cm³, melting point is 2450℃, and microhardness is 4950 kgf/mm². Its hardness is second only to diamond and cubic boron nitride. It possesses characteristics such as high temperature resistance, acid and alkali corrosion resistance, high strength, high chemical stability, and low specific gravity, making it an ideal material for many industries.
