Boron Carbide is smelted from boric acid and powdered carbon in
electric furnace under high temperature. It is one of the hardest
man-made materials available in commercial quantities that has a
finite melting point low enough to permit its relatively easy
fabrication into shapes. Some of Boron Carbide’s unique properties
include: high hardness, chemical inertness, and a high neutron
absorbing , cross section.
