Alumina Seal Ceramic Rings / Industry Insulation Rings
1. Description:
Alumina seal ceramic rings / industry insulation rings have the performances as follows:
1) 99.70% corundum 1800℃1650℃--1700℃ Corundum crucible has good
high temperature insulation and mechanical strength in oxidation
and reduction atmosphere. The thermal conductivity is large, and
the thermal expansion rate is small. It does not react with air,
water vapor, hydrogen, carbon monoxide, etc. above 1700°C. The
short-term maximum use temperature is 1800℃.
2) 99.35% corundum 1750℃1600℃-1650℃ corundum crucible in oxidation
and reduction atmosphere.
3) 85.00% high aluminum 1350℃1290℃ high aluminum crucible has good
high temperature insulation and mechanical strength in oxidation
and reduction atmosphere. The thermal conductivity is large, and
the thermal expansion rate is small. Does not react with air, water
vapor, hydrogen, carbon monoxide, etc. It can be used for a long
time when the temperature of the temperature field does not change
much. The short-term maximum use temperature is 1400℃.
2. Feature Advantages:
1) Refractory, High Temperature Resistance, Maximum Used
Temperature: 1800 ºC (3272ºF)
2) Hardness Strength, Wear Resistance Up To Mohz 9.0 ; HRA 80-90
3) High Voltage, Good Insulation Performance ,Electrical
Resistivity Up To 10∧14 Ohm.Cm
4) High Polished Surface Up To Rz0.8(Ra0.1)
5) Superior Mechanical Strength, MAX 10 MPa.m1/2 Fracture toughness
6) Pressure Resistance, Max 2300MPa compressive strength
7) Anti-High Corrosion Resistance, Such As Acid Alkali Resistance
8) Long Service Life
9) Other excellent property
