Sinyo Hexagonal Boron Nitride powder Hexagonal Boron Nitride which commonly referred to other name "white graphite", it is a man made material at high temperature over 1400℃. There are several synthesis methods. Our platy shape hBN is synthesized by boric acid and melamine at 2000℃ high temperature which resulting product has excellent high temperature stability and lubricating properties.  Hexagonal Boron Nitride is none toxic, electricity insulate, excellent lubricate at high temperature than graphite which widely used in commonly industry. Typical Application  ••• Raw material for cubic BN  • composite ceramics  • refractory  • Raw material for hot-pressed BN  • mold release for injection molding and die casting  • thermally conductive filler for organicsTypical Properties of Sinyo's Industrial platy Hexagonal Boron Nitride Powder. LNHWLN02LN05LN10LN20HW05HW10Size Distribution (um)1-34-78-1215-304-68-12Crystal size(um)<13-5Purity(BN%)98%min99%minB2O3%0.8%max0.3%maxTap density(g/cm3)0.2-0.30.25-0.35Total O%1.2%max0.7%maxAdvise application• composite ceramics • refractory • hot-pressed BN • mold release • thermally conductive filler• Industrial lubricate, • Release coatings, • Electronics industry, • Ceramic, • cBNManner of packing: 10kg in two layers PE bag and packed in a carton;                                 1kg in aluminum film bag, 10bags in a carton;We exhaust our ability to offer our customers the best quality and services all over the world.
