Ceramic Half Ring for Polysilicon Ingot

Boron Nitride Ceramic in Crystalline Silicon Production

Boron Nitride Ceramic is one kind of advanced ceramics which is suitable for vacuum or innert gas condition. It has excellent thermal properties like high temperature resistance, high thermal conductivity, low coefficient of thermal expansion (high thermal shock resistance) and good electrical property, it is the best ceramic material using for high temperature insulation. The character of machinability enable it to be made into high precision parts. Therefore, boron nitride is usually used for rapid heating equipments, as insulating parts for polycrystalline silicon ingot furnace. The heating elements will be protected by boron nitride parts in high temperature furnace.
