Boron carbide is an important engineering ceramic material, its hardness is second only to diamond and cubic boron nitride, as the third hard material, and boron carbide also has excellent neutron absorption, high wear resistance, chemical stability and other properties.

In the past thirty or forty years, due to the rapid development of science and technology, there is an urgent need for materials with special properties. Boron carbide is an important special ceramics with many excellent properties.

Boron carbide is widely used in structural ceramics, wear-resistant materials, bulletproof armor, nuclear industry, etc., which has very important application value and irreplaceable status.

Due to the limitations of boron carbide itself, it is difficult to improve its mechanical properties greatly through process optimization, but with the development of ultrafine powder preparation technology and the development of effective sintering additives, it is possible to make the conventional sintering of boron carbide, boron carbide materials have been important applications in civil, aerospace and military fields.
