Originally discovered in mid 19th century as a byproduct in the production of metal borides, boron carbide was only studied in detail since 1930.
Properties
Density: 2.51 g/cm3
Crystal structure: Rhombohedral
Melting Point: Around 2,450�
Very high hardness: It is third hardest material next to diamond and
Cubic boron nitride (CBN).
Thermal expansion coefficient: 5X10-4�-1
Boron carbide has a high neutron absorption cross section
Thermal neutron is around 4, 000 barns. And the price is much less than pure boron.
Electrical conductive: Electrical resistivity at 25C is 0.1-10 ohm. cm
