Buy Hexagonal Boron Nitride Industrial PowdershBN powders are formed by reacting naturally occurring mineral boric acid, H3BO3, with N, usually from NH3 under different temperatures and pressures that will create powders with varying purity, size, and degrees of crystallinity. These different powders, similar to graphite in their platy, hexagonal crystals, will have very different properties leading to disparate applications involving soft cosmetics and lubrication, to very hard industrial abrasive applications. The combination of thermal conductivity and dielectric properties also lead to hBN powders in their many forms being a major component in polymer-based thermal management. Precision Ceramics can help you understand which powder is best for your application.
Cubic boron nitride, cBN, is generally made from hBN powders. As graphite can be transformed into diamond, so hBN can be transformed into cBN in similar high-temperature, high-pressure processes. Cubic BN is extremely hard, second only to diamond. cBN is also sold by the carat and priced like diamond. Precision Ceramics does not handle cubic boron nitride.

About Hexagonal Boron Nitride Industrial PowdersBoron Nitride Powder has properties and structure similar to that of graphite. Its excellent dry lubricating properties and inertness to molten metal and salts has made it one of the most popular industrial lubricants available today. Boron Nitrides unique properties of high thermal conductivity, excellent lubricating abilities, and low electrical conductivity make it useful in a wide variety of applications from mold release agents to electrical insulators.
Boron Nitride Powder is an exceptional replacement for many other frequently used lubricants with metals processing such as molybdenum disulfide, graphite, and organic oils and waxes. Typically, substituting Boron Nitride Powder for these lubricants will significantly improve the operational efficiency.
Of all solid lubricants available today, hexagonal boron nitride has the highest temperature resistance in air. It can sustainably be used at approximately 900°C while other solid lubricants will start to oxidize and lose their lubricating properties at much lower temperatures. Boron Nitride’s friction coefficient stays almost perfectly unchanged over a large range of temperatures.
