Zirconium Dioxide, commonly known as Zirconia, is a high-performance ceramic material that exhibits excellent mechanical properties such as high hardness and fracture toughness. This makes zirconia ideal for a variety of wear resistance applications.
It is difficult to manufacture zirconia in large sizes compared to other oxide materials like alumina. In addition, zirconia is a relatively expensive material, and its use is usually limited to small parts/components which require high bending strength and resistance to fracture, chipping, and cracking.
Key Properties
■High strength
Zirconia is an exceptionally strong ceramic. Due to its high bending strength and fracture toughness, it resists cracking, bending, or breaking. It can also withstand severe impacts and heavy loads.
■Low thermal conductivity
Zirconia is an excellent thermal insulator due to its very low thermal conductivity.
■Good Chemical Property
Zirconia resists acid and alkali attacks.
■Excellent wear resistance
Zirconia is a popular material for parts used in high friction environments.
Application
■High load-bearing parts
■High impact-resistant parts
■Cutting tools such as blades and knives
■Heat insulation parts
■Pump parts & valve components
■Wear-resistant parts
■Pistons & liners
