Product Description
Wear Resistant Zirconia Ceramic Extrusion Dies
(1). Excellent in electrical insulation;
(2). High hardness and wear/corrosion resistance;
(3). High working temperature;
(4). Good thermal shock resistance;
Zirconia is an extremely refractory material. It offers chemical and corrosion inertness to temperatures well above the melting point of alumina. The material has low thermal conductivity. It is electrically conductive above 600° C and is used in oxygen sensor cells and as the susceptor (heater) in high temperature induction furnaces. With the attachment of platinum leads, nernst glowers used in spectrometers can be made as a light emitting filament which operates in air.
1. Key Properties of Zirconium Oxide
Use temperatures up to 1000° C
- High density
- Low thermal conductivity (20% that of alumina)
- Chemical inertness
- Resistance to molten metals
- Ionic electrical conduction
- Wear resistance
- High fracture toughness
