Abstract
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.
