Use

Boron nitride (bn) powders can be used as mold-release agents, high-temperature lubricants, and additives in oils, rubbers, and epoxies to improve thermal conductance of dielectric compounds. powders also are used in metal- and ceramicmatrix composites (mmc and cmc) to improve thermal shock and to modify wetting characteristics.the platy habit of the particles and the fact that boron nitride is not wet by glass favors use of the powder as a mold wash, e.g., in the fabrication of high-tension insulators. it is also useful as thermal insulation in induction heating.
