ABSTRACT:
Non laminating anisotropic boron nitride is prepared by reacting a boron halide with ammonia at a temperature of from 1100.degree. C. to 1600.degree. C. in the presence of a small amount of a volatile oxygen containing compound. The small amount of volatile oxygen containing compound is sufficient to prevent lamination yet small enough to prevent the finalized product from losing its anisotropy.
