Zirconia - stabilised with Yttria Cylindrical Crucible is part of Goodfellow's range of ceramic crucibles. Yttria-stabilised zirconia is a ceramic material that exhibits high strength and fracture toughness at high temperatures. We have a wide range of 38 sizes available, with diameters ranging from 10mm to 150mm. These crucibles are designed for use in high temperature laboratory furnaces and industrial processes. Example applications include melting metals, growing single crystals and sintering powders into solid shapes. The crucibles provide a high purity and inert environment for processes at temperatures exceeding 1000°C.
