Product description
Hot Pressed Boron Nitride has the highest operating temperature in inert gas and vacuum environment. It has excellent electrical insulation, high thermal conductivity, low thermal expansion coefficient, excellent thermal shock resistance, it is usually used for electrical insulating components for high temperature furnace. It can be used as metal smelting crucibles because it will not react with most molten metals. Moreover, Boron Nitride can be quickly machined into high accuracy components by the normal mechanical machining methods. There are several types of Boron Nitride Ceramics available in Mascera, the most typical is BN99 with 99% Purity.
