Abstract

The invention disclosed herein relates to a body of substantially pure isotropic boron nitride in which individual anisotropic crystals of boron nitride are substantially randomly oriented and pyrolytically bonded to form a body having substantially improved electrical and mechanical properties compared with anisotropic boron nitride bodies in which individual boron nitride crystals are hot press bonded.
