OEM Large Size Industrial Customized Alumina Ceramic dics for heat
insulation
Description:
Alumina ceramic disc is used in high temperature sintering
furnace,Play the role of mat burning and Can have the effect of
insulation.The advanced ceramic discs are made from high purity
alumina which is up to 99.9%. They were formed via cold/hot
isostatic pressing, dry pressing, and tape casting with a very
dense and smooth texture.
Principal characteristic of OEM Large Size Industrial Customized Alumina Ceramic dics for heat
insulation:
1. Thermal characteristics: heat resistance and thermal
conductivity
