Purity: *8%***9.9% Particle size: 0.****0mircron packing:according customer's request For more information, please contact with us freely General Characteristics of Boron Nitride 1) Electrical Insulator 2) Low Dielectric Constant and Loss 3) High Temperature Stability 4) Thermal Conductor 5) Lubricious 6) Inert 7) Non-Wetting Features: It is a white powder, with hexagonal crystal. Similarto pot lead, theoretical density 2.*9, ball hardness**2, lubricant well, general named white pot lead; melting point ****0C, the thermostable to ****0C; in the atmosphere over ****0C, oxiding markedly; stability well on chemistry having corrosion-resistance for various mineral acid、slkali、salt solution and organic solvent. Particularly having well-off corrosion-resistance for melting meltal aluminium iron and glass etc; electric-insulability well, heat condctivity well too, little thermal-expansivity andthermal vibrativity resistance well. Applications: 1、May be used as a ddition agent for plastic resin. etc, polymer It is possible to increase the strength of these materiats and thermal-resistance, corrosion-resi-stance and radioresiatance. 2、May be used as the grease for anti-oxidation and watcrproof. 3、May be used as the catalyst for organism dehydrogenated composite rubber and platinum rearranging process. 4、May be used as the thermal sealing dry agent for transistors. 5、May be used as the maternium for aluminium evaporated container. 6、Boron nitride and titanium are hot pressd to form titanium diboride. The composition of titanium nitride and boron nitride features higher thermostability. a-nti-oxiding and anti-washing. 7、May be used as a sold lubricant and a anti-rubbing material. 8、May be used as spercific electrolyzing and resistance mater-iasat the high temperature. 9、May be used as a adsorbent for benzene. *0、May be compressed and made into various shape materials for different usages
