By boron carbide powder pressed into products: sand jet nozzle seal ring bearing mud pump plunger pestle and rocket launcher warship helicopter as a new type of material such as ceramic coating, high melting point high hardness, high elastic modulus of strong wear resistant force since embellish sex is good wait for a characteristic and is widely used in sandblasting machinery and electronics information aerospace automobile and other industries. 

The proportion of boron carbide is 2.52kg per square meter, the melting point is about 2450, and the boron carbide is a hexagonal crystal system with dark black color, which will not react in acid-base solution. Boron carbide also has the characteristics of high chemical potential, good thermal neutron capture cross section, large amount of neutron absorption and non-magnetic semiconductor conductivity, and high grinding efficiency.

Boron carbide is suitable for all kinds of cemented carbide cutting tool cutting precision components, such as mould etc. Grinding abrasive polishing, drilling and high-temperature refractory wear-resistant electrode material for making metal boride boron alloy boron steel engineering ceramics such as the main raw materials, manufacturing has been applied in recent years in the military field and space technology, is an indispensable material industry at present.
