We can supply Boron Nitride with min.98%. It is white powder in hexagonal crystal structure Due to its good lubricant character it is also called white graphite Theorectical density 2.29 Mohs hardness 1-2 Melting point 3000 It can be oxidated greatly when temperature over 1000 It shows good chemical stability and corrosion-resistance to various inorganic acid alkali salt solution and organic solvent Especially good corrosion-resistance to melting Aluminum Iron metal and glass can be found Application 1. As additives to polymer such as plastic resin for strengthening their intensity thermal-resistance corrosion-resistance and radio-resistance 2. As lubricator it is used to anti-oxidation and waterproof 3. As catalyst for dehydrogenating of organism and rearrangeing process of sythentic rubber and platinum 4. As thermal sealing dry agent for transistors 5. As material for Alumimum evaporateing container 6. Material which are hot pressed with Boron Nitride and Titanium shows good thermal- resistance, anti-oxidation 7. As solid lubricant and wear-resistance material 8.
