Nitrides, Silicides and Sulfides
Nitrides contain very high melting point but initiate to oxidize at low temperature. They have poor resistance also to chemicals. Boron nitride have a graphite structure and thus exhibit lubricating properties. A type of boron carbide identified as Borazon produced via compressing beneath high pressure of 68000 atmospheres at a temperature above 1700oC has hardness equivalent to such of diamond. Borazon also has a excellent resistance to oxidation and can withstand a temperature of 1950oC.
