China wholesale Nano Zinc Powder - BN 50nm 99.9% – Runwu

BN 50nm 99.9%

The main characteristics of nano boron nitride ultrafine boron nitride powder prepared by a special process method, the powder of high purity, small particle size, than the large surface area and high surface activity, the crystal structure similar to graphite layered structure, showing the loose lubrication easy to absorb moisture (modified after moisture absorption problem can be overcome), light weight traits; excellent dry lubrication, chemically extremely stable, low thermal expansion coefficient, excellent high temperature thermal insulation materials; Mohs hardness of 4 hardness close to diamond, thermal stability and chemical properties superior to other materials.

Applications
The thermal insulation of the heat sealing of a transistor desiccant and plastic resin, rubber coating polymer additives;
Two drill bits, abrasives, cutting tools;
Three high-temperature lubricants and release agents;
Four high-voltage high-frequency electric insulators and plasma arc, automatic welding of high temperature stent coating materials of the high-frequency induction furnace, semiconductor, solid-phase admixture, atomic reactors, structural materials, packaging materials to prevent neutron radiation, radar The transfer window, the media of the radar antenna and the composition of the rocket engine materials.
