Main features: Nano-boron nitride and
ultra-fine boron nitride powder are prepared by special process. The powder has
high purity, small particle size, large specific surface area, high surface
activity, and the crystal structure has a graphite-like structure, which is
loose and lubricious. Easy to absorb moisture (can overcome the moisture
absorption problem after modification), light quality and other traits;
excellent dry lubrication ability, extremely stable chemical properties, low
thermal expansion coefficient, excellent high thermal conductivity insulating
material at high temperature; Mohs hardness 4, The hardness is close to that of
diamond, and its thermal stability and chemical properties are superior to
other materials.
Application field：
1. Heat-sealing desiccant of transistor;
thermal insulating insulation additive of polymer such as plastic resin rubber
coating;
2. Drill bits, abrasive materials,
cutting tools;
3. High temperature lubricant, release
agent;
4. High-voltage
high-frequency electric and plasma arc insulators, automatic welding high
temperature resistant stent coating, high frequency induction furnace
materials, semiconductor solid phase admixture, atomic reactor structural
materials, neutron radiation prevention packaging materials, radar The transfer
window, the medium of the radar antenna, and the composition of the rocket
engine. |
