A molten potassium hydroxide before being decomposed in the red hot chlorine and it reacts under conditions

Avoid light, open flame, heat. Graphite similar nature, good electrical insulation, thermal resistance and chemical resistance. Very strong oxidation resistance at high temperatures, also has good lubricity, is an excellent high-temperature solid lubricant. Has a strong neutron absorption ability. grinding wheel stable, for almost all of the molten metal were tested chemically inert. BN does not dissolve in water, boiled with water hydrolysis is very slow, resulting in a small amount of boric acid Polycrystalline diamond. With weak acid and alkali are not react at room temperature, slightly soluble in hot acid, treated with molten potassium hydroxide before being decomposed, chlorine only in conditions below red heat reacts with it. To high temperature to 2000 ℃. Easy machining with excellent performance. Cubic boron nitride and diamond considerable hardness, high temperature stability than the diamond.
