Hot Pressed Boron Nitride (HPBN) Ceramic has the highest operating temperature in inert gas and vacuum environment. It has excellent electrical insulation (the breakdown strength is 4 times of Alumina Ceramics), high thermal conductivity, low thermal expansion coefficient, excellent thermal shock resistance, it is usually used for electrical insulating components for vaccum furnace. It can be used as metal smelting crucibles because it will not react with most molten metals like Cu, stainless steel, Fe, Sn, Zn and Sb. Moreover, Boron Nitride can be quickly machined into high accuracy components by the normal mechanical machining methods.
Typical Applications of Boron Nitride parts:
●Electrical Insulating parts for vacuum furnace/polysilicon ingot furnace/semiconductor device
●Crucibles or containers for high purity molten metals
●Break rings for continuous casting of metals
●Ceramic nozzles for metal powder gas atomization
●Heat resistant ceramic parts
Mascera produces Boron Nitride materials with different composition:
●99% Boron Nitride
●BN + Ca
●BN + Al2O3
●BN + ZrO2
●BN + AlN
