Boron carbide ceramic powder's preparation and development

2018-04-19
Boron carbide is a kind of superhard material with similar mechanical properties to diamond. It has been widely used in armor coating and other weapons. The main preparation process of boron carbide ceramics is powder preparation, molding and sintering, a typical powder metallurgy process.
Composite additives can greatly reduce the sintering temperature and pressure, and can obtain high-density pure boron carbide ceramics under high temperature and high pressure, and have excellent mechanical properties.
The development and application of high-performance, low-cost boron carbide ballistic ceramic materials can greatly increase the performance of related weapons and equipment, with significant military and economic benefits.
