Zirconia /Zro2 /Zirconium Oxide Ceramic Crucible
China Zirconia /Zro2 /Zirconium Oxide Ceramic Crucible, Find details about China Zirconia Crucible, Zirconia Crucible for Melting from Zirconia /Zro2 /Zirconium Oxide Ceramic Crucible
Zirconium oxide ceramics also have very high thermal expansion and are therefore often the material of choice for joining ceramic and steel.
Components made from this material are more expensive than components made of alumina ceramics. Zirconium oxide ceramics are used among other applications, as tools for wire forming, as auxiliaries in welding processes, as materials for crowns and bridges in the dental industry, as insulating rings in thermal processes, and as oxygen measurement cells in lambda probes.
