Zirconia

Zirconia is an extremely hard refractory material.

It offers chemical and corrosion inertness to temperatures well above the melting point of alumina.

The material has low thermal conductivity.

• Use temperatures up to 2400°C
• High density
• Low thermal conductivity (20% that of alumina)
• Chemical inertness
• Resistance to molten metals
• Ionic electrical conduction
• Wear resistance
• High fracture toughness
• High hardness
