Hexagonal (graphitesimilar)

High - quality powders

    JSC "Zaporozhsky Abrasivny Combinat" has one of the biggest production capacities of hexagonal Boron Nitride in the world.

    BORON NITRIDE - is the material obtaining unique properties, due to which it is considered to be indispensable material for application in various branches of industries.

    BORON NITRIDE is simultaneously a superb dielectric and heat insulator owing to what it serves a unique material to be used in electronic devices of a special destination.

    BORON NITRIDE is a nontoxic, inert to the majority of melted metals and chemical reagents substance.

    However BORON NITRIDE main application - super-hard material synthesis: borazon, cubic and wurtzitesimilar boron nitrides.
