Description
3-50mm High Alumina Resistor Ceramic Rod White Zirconia Ceramic Plunger
Size: as your requirements.
Delivery time: depend on the quantity.
Materials：95%~99.9%Alumina (Al2O3)ceramic/ Zirconia(ZrO2) ceramic /Silicon nitride ceramic /Silicon carbide ceramic/Aluminium nitride ceramic.
Zirconia ceramic also called engineering ceramic, the zirconia ceramic plunger have excellent wear and corrosion resistance. It has good performance on hardness and strength.
Features of zirconia ceramic plunger:
1.Excellent mechanical strength
2.Excellent wear resistance
3.High impact resistance
4. High hardnes and fracture toughness
5.Low thermal conductivity (20% that of Alumina)
6.Good chemical resistance
7.Ionic conductivity
Note: The shape(outter diameter&length), surface roughness and tolerance can be customize.
