Boron Carbide

Boron Carbide is a black, crystalline compound and is one of the hardest known materials and is the hardest material produced in tonnage quantities. Production of Boron Carbide is by a carbo-thermal reduction of Boron Oxide (B2O3) with carbon in an electric arc furnace. The resultant material is then crushed, ground and screened to specific powder sizes.

With its combination of high strength, chemical inertness, low density and hardness, Boron Carbide has many applications including:


As an abrasive medium for grinding, lapping and polishing applications. Material is supplied to international FEPA macro and micro grit sizes or to customer specifications.

For metal matrix composites, we are able to supply Boron Carbide classified down to near sub-micron sizes. And for non-oxide ceramics, as a Boron source for the production of Borides.

For further fabrication we offer boron carbide powder as feedstock for the production of nuclear rods, pellets and shielding components, wear resistant components, nozzles for abrasive cutting or blasting, and ballistic armour.

Hot Pressed and Sintered Components (density >2.48 g/cm3)

For vehicle or body armour we can supply Boron Carbide in the form of hexagons or squares with thickness's up to 25mm.

For nuclear components we offer Boron Carbide to individual customer drawings and specifications. A range of machining operations, e.g., edge chamfering, holes and bonding can be applied as required.

For wear resistant and blasting nozzles ABSCO Limited supplies a range of standard Boron Carbide nozzles or nozzles produced to individual customer drawings.
