Polysilicon Furnace BN Ceramic Shim

The boron nitride ceramic has excellent properties of high temperature resistance, high thermal conductivity, high electrical
Insulation and easy processing, high processing precision, low density, lubrication, non-toxic, is an ideal high temperature
thermal conductivity of insulation materials.

Insulated tiles,pad,gasket,base for polysilicon ingot furnace can avoid the past corundum fracture under rapid heating process and erosion in silicon atmosphere, with long use life, little pollution to products, etc.

Our boron nitride ceramic insulation part has the following characteristics:
1 BN ceramic material has tight structure, high compressive strength and low porosity;
2 organization fine, no cracks, no delamination;
3 use temperature can be above 1750 degrees;
4 small coefficient of thermal expansion.
In actual use,Polysilicon Furnace  boron nitride ceramic Shim surface is not easy to be carburizing, high corrosion resistant in silicon atmosphere, long service life
