Application
1.Abrasives
Due to its high hardness,boron carbide powder is used as an abrasive in ploishing and lapping applications,and also as a loose abrasive in cutting applications such as water jet cutting.It can also be used for dressing diamond tools.
2.Refractory
With the perfect characteristics in physics and chemistry,boron carbide has a high melting point ,to use as senior fireproof
material of warplane.
3. Nozzles
The extreme hardness of boron carbide gives it excellent wear and abrasion resistance and as a consequence it finds application as nozzles for slurry pumping,grit blasting and in water jet cutters.
4.Nuclear applications
Its ability to absorb neutrons without forming long lived radio-nuclides make the material attractive as an absorbent for neutron radiation arising in nuclear power plants.Nuclear applications of boron carbide include shielding,and control rod and shut down pellets.
5.Ballistic Armour
Boron carbide ,in conjuction with other materials also finds use as ballistic armour(including body or personal armour)where the combination of high elastic modulus,and low density give the material an exceptionally high specific stopping power to defeat high velocity projectiles.
6.Other applications
Other applications include ceramic tooling dies,precision toll parts,evaporating boats for materials testing and mortars and pestles.
Storage
Store in ventilated and cool warehouse.
