  • Crystallization behavior of cubic boron nitride from an ...

    Cubic boron nitride (c-BN), which possesses a diamond-like zinc-blend structure, is the second hardest and the second most thermal conductive material after diamonds, and c-BN is even superior to diamonds in terms of chemical resistance to ferrous alloys and oxidation . c-BN has therefore been employed for making cutting tools for steel materials.

    Cubic boron nitride is a synthetic crystalline material second only to diamond in Knoop hardness. Although softer than diamond, CBN is superior in terms of abrasion resistance and oxidation resistance with steel alloys. Its relative crystalline inertness makes CBN the abrasive of choice for grinding steels, cast iron and nickel-based alloys.

  • Boron carbide - Wikipedia

    Boron carbide (chemical formula approximately B 4 C) 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.
