Boron carbide​ is the superhard material whose hardness is only second to diamond and cubic boron nitride, with hardness up to 3000 kg/mm2. Low density, only 2.52g /cm3, is 1/3 of steel; High elastic modulus, 450 GPa; High melting point, about 2447℃; Its thermal expansion coefficient is low, high thermal conductivity. Boron carbide is a kind of nonmetallic ceramic material, gray black, has many excellent physical and chemical properties Read More »

In everyone's impression, ceramics is fragile, but after modern technology processing, ceramics "suddenly changed", has become a hard, high strength new material, since the 21st century, bullet-proof ceramics developed rapidly, there are many kinds, including alumina, silicon carbide​, boron carbide, silicon nitride, titanium boride, etc. Among them, alumina ceramics (Al2O3), silicon carbide ceramics (SiC), boron carbide ceramics (B4C) are widely used.

Boron carbide​, also known as Black Diamond, is an organic form. The molecular form IS B₄C. It is usually a grayish-black fine powder. It is one of the three hardest materials known (the others are diamond and cubic boron nitride) and is used in many industrial applications. It has a Mohs hardness of 9.3. So what are the properties and chemical properties of boron carbide? Read More »
