chemical corrsion resistance zirconia ceramic plate
zirconia ceramic plate, mechanical ceramic sheet, industrial ceramic plate,
structure ceramic tplate, electric ceramic plate
Feature:
1.usgae for grind & disperse
2.super fine raw material
3.high strength at high temperature
4.high hardness& toughness
5.excellent mechanical property
6.chemical corrosion resistance
Application:
Zirconia ceramic is one of the most useful ceramic materials.
It has superior mechanical strength and wear resistance,
its tenacity is 3-4 times that of alumina and it offers superior heat insulation.
The usage is blaco for heat insulation, guide spacer, nozzles, metal fittings, pump parts.
