Boron Nitride Crucilbes and Containers for Molten Metals
Boron Nitride Solids are made by hot pressing hexagonal Boron Nitride powders. The color of BN products is milky, true density is 2.27g/cm , Mohs value is 2, they have a high melting point(sublimate point is 3000°C). When in a condition of inert atmosphere, their maximum service temperature can reach to 2800°C. Their thermal conductivity is 25W/(m·K), similar to stainless steel.And coefficient of liner And coefficient of liner expansion is between 2.0×10 /°C to 6.5×10 /°C. They have a high quality of heat-resistance and shock-resistance, and they can work efficiently after several hundred of 1000°C←→20°C cycles. Their oxidation resistance is poor, and their chemical properties are stable, they have a high corrosion-resistance of acid, alk, molten metal and glass. BN products cannot have chemical reaction with most molten metals, such as Cu, stainless steel, Fe, Sn, Zn and Sb. Mechanical strength is low, just a little more than that of graphite, volume resistance is between 25~1050°C,10-6~10-6n·cm, they are good insulators. Electric breakdown strength is between 30 kV/cm to 40 kV/cm, which is three times than that of aluminum oxide. Thermo compression products are distinctly anisotropic, they can be used to finish cut, and the precision of lathe can reach to 0.01mm.
