Yttria-stabilized Zirconia Point Bottom Crucible

Formula: ZrO₂/Y₂O₃
Form: Crucible
Material: Zirconia - stabilized with Yttria
CAS Number: 114168-16-0
Commodity: Ceramics
Goodfellow's Zirconia - stabilised with Yttria Point Bottom Crucibles are high-performance ceramic crucibles used in materials research and industrial high-temperature applications. They have excellent chemical inertness, superior thermal shock resistance to temperatures reaching up to 2200°C, and good corrosion resistance to acids and alkalis. Available in 8 size variations, they are ideal for applications requiring a crucible that is exceptionally strong, wear-resistant and chemically inert at extremely elevated temperatures.
