  • Applications

    Boron nitride (CAS 10043-11-5), in forms such as hexagonal BN (h-BN) and cubic BN (c-BN), finds widespread use across industry: it serves as a high-temperature solid lubricant in bearings, seals, and furnaces; cubic BN powder is used as an abrasive in cutting and grinding tools; it acts as a functional filler in polymer and ceramic composites to enhance thermal conductivity and electrical insulation; it is added to refractories and ceramic matrices to improve mechanical strength and thermal stability; BN-based coatings provide wear resistance and chemical inertness; and it is employed in electronics packaging and thermal management as a dielectric, thermally conductive filler, and part of heat-spreading materials.
