1.4 Melting point: 3000℃(stable in the inert atmosphere)
1.5 Mohs′ hardness: 1-2.
1.6 Density: 2.29g/cm3
1.7 Solubility: Insoluble in water, slightly soluble in hot acid.
1.8 Properties: Hexa-boron nitride has excellent electrical properties of electrical insulating, thermal conductivity, corrosion resistance and good lubrication. It has the strong ability of neutron absorption. With chemical properties of stability, it has corrosion resistance to various inorganic acids, alkali, salt solutions and organic solvents. So does all melting metals. Physical and chemical properties unchanged under 1000℃. The temperature can reach 3000℃ when used in nitrogen and argon. H-type hexa-boron nitride powder is autoclaved to become white block, and easy to processing. Heat resistance temperature reaches 2000℃.
