Boron Nitride

Another interesting chemistry is high purity boron nitride (BN) powders, which have been shown to improve the lubricity in a variety of plastics matrices. BN is a natural lubricant, which is used to improve parts, which must be highly resistant to wear. It is also thermally conductive and an electrical insulator and can bring these properties to a plastics compound, as well as providing nucleation. The powders from Advanced Ceramics are large single-crystal materials with mean particle (crystal) sizes of 50 and 35 microns, respectively. Typical BN crystals are 15 microns or smaller, and agglomerates are also produced giving larger particle sizes, or over 250 microns.
