PBN crucible / tube / plate High Purity BN / Boron Nitride Ceramic Crucible with Lid
Product Description
Boron nitride ceramic has good heat resistance, thermal stability, thermal conductivity and high temperature dielectric strength. It is an ideal heat dissipating material and high temperature insulating material. Boron nitride has good chemical stability and is resistant to most of the molten metal. It also has good self-lubricating properties. Boron nitride products have low hardness and can be machined with an accuracy of 1/100 mm.
Boron Nitride ceramic 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.
