The disclosure is directed to compositions and methods for forming boron nitride coatings, using polymers derived from tri-substituted borazine and chloroborazine compounds. The polymeric compounds are mixed with ammonia, pyrolized at high temperatures to obtain a high temperature melt, and further converted to boron nitride coatings on various substrates. The polymeric compounds can be stored prior to pyrolysis.

Precursors for boron nitride coatings

The disclosure is directed to polymeric B-aminoborazene compounds suitable for pyrolytic conversion to boron nitride. The B-aminoborazine compounds are preferably mixed with an organic solvent and a cross-linking agent to form a polymeric gel. The polymeric gel is then pyrolized to form boron nitride. The polymeric gel is useful to coat various forms and materials.
