Boron nitride 1.ISO/SGS 2.Manufacture 3.CAS No. 10043-11-5  Boron Nitride 1.CharactersMolecular formula BNMolecular weight 24.81Melting point3000°C(It is stable during inert gas)Density2.29g/cm3Solubility insoluble in water. -------------------------------------------------------------------------------------------------------------------2.SpecificationsQuality standard (QJ/YH 02.08-89) ItemIndexGrade AGrade BBoron nitride (BN) % ≥98.095.0Water soluble boron oxide (B2O3) % ≥1.01.5-------------------------------------------------------------------------------------------------------------------3.PropertiesWhite loose powder, insoluble in cold water. With similar properties with graphite, so is called as "White Graphite". Melting point 3000°C. At neutral reducing atmosphere, it can resist high temperature as 2000°C. In the air, it will be oxidized above 1000°C. It has stable chemical properties, high electric insulativity, heat conductivity and chemcial corrosion resistance, and is easy to be processed mechnically.-------------------------------------------------------------------------------------------------------------------4.UseIt is widely used in high-temperature, high-frequency and plasma insulator, high-temperature resistant coating, high-frequency induction furnace, semiconductor, atomic pile, nuclear radiation resistance, radar, rocket engine, high-temperature lubricant, form release agent and other high-temperature resistant products.-------------------------------------------------------------------------------------------------------------------5.Package&StorgeIt is vaccum-packed in aluminium foil bag, in which is put plastic bag. Net weight 1kg a bag.It should be stored in a shady, ventilating and dry storehouse. Its shelf life is one year. The product can be still used if up to standard through retest after the specified date.Boron nitride 1.ISO/SGS 2.Manufacture 3.CAS No. 10043-11-5 BorBoron nitride1.ISO/SGS2.Manufacture3.CAS No. 10043-11-5  Boron Nitride 1.CharactersMolecular formula BNMolecular weight 24.81Melting point3000°C(It is stable during inert gas)Density2.29g/cm3Solubility insoluble in water. -------------------------------------------------------------------------------------------------------------------2.SpecificationsQuality standard (QJ/YH 02.08-89) ItemIndexGrade AGrade BBoron nitride (BN) % ≥98.095.0Water soluble boron oxide (B2O3) % ≥1.01.5-------------------------------------------------------------------------------------------------------------------3.PropertiesWhite loose powder, insoluble in cold water.
