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.
