Abstract

The invention provides a method of making a boron suboxide composite material including the steps of reducing the B2O3 content of a source of boron suboxide to produce a boron suboxide of reduced B2O3 content and sintering the boron suboxide in the presence of a material capable of producing a secondary phase to produce the boron suboxide composite. The B2O3 content is preferably reduced to as low a content as possible.
