Boron Carbide Melting Furnace

Boron carbide (chemical formula approximately B4C is an extremely hard boron–carbon ceramic, and covalent material used in tank armor, bulletproof vests, engine sabotage powders, as well as numerous industrial applications. With a Vickers Hardness of 30 GPa, it is one of the hardest known materials, behind cubic boron nitride and diamond.

Boron Carbide is a synthetic material that ranks in hardness behind only Cubic Boron Nitride and Diamond. It is the hardest material produced in tonnage quantities, although much is utilized in powder form for abrasive grinding and lapping applications and abrasive water jet cutting or as coatings for nuclear applications.

Boron carbide is used in refractory applications due to its high melting point and thermal stability; it is used as abrasive powders and coatings due to its extreme abrasion resistance; it excels in ballistic performance due to its high hardness and low density; and it is commonly used in nuclear applications as neutron radiation absorbent.

Properties of Boron Carbide Powder The compound is hard boron-carbon ceramic and is widely used in industries, in the production of bulletproof vests, and tank armors. With a hardness measuring up to 9.3 on the Mohs scale, the compound is recognized as one of the hardest materials after cubic boron

We supply Boron carbide grain or micro powder produced by the standard of GB/T 2481, FEBA or JIS. We also offer super fine powder ( 2m) and special powder for engineering ceramics and nuclear industry. Boron Carbide Applications. Superior Abrasives. For polishing materials, abrasive water jet cutting and diamond abrasive material amendments.

Boron Carbide (B4C) Powder from Advanced Abrasives with a Mohs hardness of 9.5 is almost as hard as cubic boron nitride (cBN) and so serves as a lower cost alternative abrasive to both diamond and to cBN. The closely controlled grading and particle shape of this powder

A high performance abrasive material with chemical and physical properties similar to diamonds, such as chemical resistance and hardness. Boron carbide's extra hardness gives it the nickname black diamond. Color is black or gray. Due to its high hardness, boron carbide powder is used as an abrasive in polishing and lapping
