Misting Zirconia Ceramic Nozzle Thermal Shock Resistance
High Purity Zirconia Ceramic Nozzle for Misting Nozzle
Description:
Zirconia nozzles are manufactured from different type of raw materials, chemical content, physical specifications and sizes depending on the service application. We choose high quality zirconia as the main material. Zirconia has high strength, wear resistance, and flexibility far beyond those of most other technical ceramics. Zirconia is a very strong technical ceramic with excellent properties in hardness and corrosion resistance, all without the typical property of ceramics - brittleness. Its unique resistance to crack propagation and high thermal expansion make it an excellent material for joining ceramics with metals like steel.
