GA Zirconia Crucible， Composite ZrO2
Intruduction to Zirconia Crucibles
Pure zirconia (ZrO2) has an extremely high melting point of up to 2760°C and exhibits excellent chemical inertness to most commonly used casting alloys. A study has shown that ZrO2 may still be reduced by the active element hafnium (Hf) in high-temperature alloys(Valenza, Muolo, & Passerone, 2010).
WEIERT’s zirconia crucibles are made from Composite Stabilized Zirconia. Thanks to the unique physical properties imparted by Composite Stabilized Zirconia, these crucibles offer exceptional thermal shock resistance, allowing them to withstand repeated and severe temperature fluctuations without significant structural damage. This helps reduce furnace downtime for maintenance and increases casting yield.
The maximum operating temperature for these zirconia melting crucibles can reach up to 2200°C, providing higher melt cleanliness at high temperatures, which minimizes crucible contamination and impurities in molten metals. Additionally, they have a long service life and superior performance compared to crucibles made from
other materials.
Applications:
- Vacuum investment casting
- Alloy melting crucibles
- Precious metal melting crucibles
- Glass melting crucibles
Available maximum size: H 400mm x OD 300mm x Th 10mm, volume 24L
Available minimum size: H 10mm x OD 10mm x Th 2mm, volume 0.00026L
