What is boron carbide?

Boron carbide, also known as black diamond, is an inorganic substance with a chemical formula of B4C, usually gray-black micropowder. It is one of the three hardest materials known (second only to diamond and cubic boron nitride). It is used in tank armor, bulletproof vests and many industrial applications. Its Mohs hardness is about 9.5. Boron carbide is an important engineering ceramic material. Its hardness is second only to diamond and cubic boron nitride, and is the third hardest material. Boron carbide also has excellent neutron absorption, high wear resistance, and chemical stability. Such properties have played an important role in the civil, aerospace, and military fields.

The main industrial preparation methods of boron carbide

In recent years, major industrial countries have paid great attention to the development and research of special ceramics, forming a worldwide "ceramic fever" and making great progress. According to the reaction principles, raw materials and equipment used in the synthesis of boron carbide powder The industrial preparation methods of boron carbide powder mainly include high-temperature self-propagating synthesis method, electric arc furnace carbothermic reduction method, chemical gas phase reaction method, gel carbothermic reduction method, etc.


Industrial production of boron carbide often adopts the carbothermal reduction smelting method using boric acid and carbon as raw materials. This method requires a large amount of boric acid and has problems such as high energy consumption and easy introduction of impurities. In view of the above reasons, a low energy consumption is developed. , The synthetic method of boron carbide with easy control of product particle size is a meaningful thing.
