High Working Temperature 99.7% Alumina Ceramic Plate
Description:
Ceramic plate are used in many electronic applications where a thin
insulating layer of thermally stable material is required to
conduct heat away from electronic components whilst electrically
insulating them, and material is 95%, 96%, 99% alumina and
zirconia.
Properties with excellent insulation, high mechanical strength,
high thermal conductivity, low expansion coefficient, small
dielectric constant, high-temperature resistance, excellent erosion
and wear resistance, good quality in chemical shock heat and cold.

Advantages:
1.High hardness.
2.Superior abrasion and impact resistance.
3.Corrosion and chemical resistance.
4. Light weight:Its density is 3.5g/cm3, only half that of steel,
which can greatly reduce equipment load.
Application:
1. Ceramics, mines and other grinding equipment lining.
2· Material thansfer equipment.
3· Inside and outside surface of powder separating equipment on iron and steel works.
4· Thermal and power plants.
