99% Alumina Ceramic Spacer Zirconia Ceramic Insulation Washer
Alumina Ceramic Spacer Ideal for very high temperature conditions. Exceptional strength in compression and tension. Withstands very high voltage without flashover.
Alumina Ceramic Spacer electrically help to isolate components from one another. For instance, you can isolate one sample holder from another sample holder . Available in standard screw sizes. Made from 99.7%+ Al2O3(alumina), these non-porous washers are fully vacuum compatible and bakable to over 400oC.

Alumina Ceramic Spacer is an electrical insulator but has relatively high thermal conductivity (35 W/m K). In its most commonly occurring crystalline form, called corundum or a-aluminium oxide, its hardness makes it suitable for use as an abrasive and as a component in cutting tools.
Advantage of Zirconia Ceramic Electrical Insulation Washer / Spacer
1. Isostatic pressed.
2. Fire resistance.
3. Superior mechnical strength.
4. High corrosion and wear resistance.
5. High Temperature Resistance.
6. Good Insulation Performance Precision.
7. Zirconia and alumina ceramic material.
They are high corrosion and wear resistance and strong impact resistance and delivers 10 times longer working life than metal plunger. They give a longer life to the sealed packing material.
