Micropowder Black B4C Boron Carbide Powder For Ceramic Coating
Boron carbide, alias black diamond, is usually colored powder.It is one of the three hardest materials known (the other two are diamond and cubic boron nitride) and is used in tank armour, bulletproof suits and many industrial applications. It is used in wear-resistant materials, ceramic reinforced phase, especially in light armor, reactor neutron absorbent, etc.
