Introduction 
 
Zirconia offers chemical and corrosion resistance to temperatures well above the melting point of Alumina. In its pure form crystal structure  changes limit mechanical applications, however stabilized Zirconias produced by addition of Calcium, Magnesium or Ytrium Oxides can produce very high strength, hardness and particularly toughness. In addition the material has low thermal conductivity and is an ionic conductor above 600°C. This has lead to applications in oxygen sensors and high temperature fuel cells.

Features
 
1).Excellent insulation, security, long working life.
2).High temperature resistance
3).Resistance to electric breakdown
4).Stand wear and tear
5).High strength
6).Corrosion resistance
7).Good compactness
8).High hardness

Application
 
Insulators, capacitors, resistors, furnace tubes, sealing refractory parts, foundry shapes, wear pads,thermocouple protection tubes, cutting tools and polishing/grinding powders, ballistic armor, laboratory equipment, bio-ceramic parts for orthopedic and dental surgery, bearings.
