Covers for High Purity Zirconia (ZrO2) Crucibles
High purity zirconia (ZrO2) crucibles have excellent wear, chemical and temperature resistance. It can withstand high temperature up to 2100°C. It is ideal for the application which requires the temperature higher than Alumina crucible withstand temperature (1600°C), such as melting of precious metals and super-alloys which have melting point higher than 1800°C.
These crucible covers can be used to avoid split of liquid chemicals or create a low oxygen environment during calcination.
Maximum temperature: 1800°C (air); 2100 °C (Nitrogen or Vacuum)
