Boron Carbide (B4C)
Tucson, Arizona, USA
Skyline Components, LLC
Boron carbide is one of the hardest materials available in commercial
shapes, and gives outstanding resistance to abrasive wear. It has a
low density but a high elastic modulus and high compressive strength.
B4C can be polished to a mirror finish and has good resistance to
acids, but not to alkali hydroxide melts. It is refractory and chemically
inert, but less resistant to oxidation than silicon carbide..

We can supply boroncarbide ceramics in shapes
of crucible, tube, rod, plate, disc, wafer, ring,
nozzle, ball and so on.
