ABSTRACT:
High density, sintered refractory articles composed of: 60 to 98% by weight of boron carbide and 2 to 40% by weight of silicon carbide, and 0 to 10% by weight of aluminum. As a result of the composition, products with densities in excess of 94% of theoretical can be produced by cold pressing followed by a pressureless heat treatment.
