BORON NITRIDE AGGLOMERATED POWDER

摘要

A novel composite structural component including novel boron nitride agglomerated powders and a matrix is provided having controlled density and fracture strength features. In addition methods for producing the novel boron nitride agglomerated powders are provided. One method calls for providing a feedstock powder including boron nitride agglomerates, and heat treating the feedstock powder to form a heat treated boron nitride agglomerated powder. In one embodiment the feedstock powder has a controlled crystal size. In another, the feedstock powder is derived from a bulk source.
