Crucibles Made of Magnesia-stabilised Zirconium Dioxide Description
Magnesia-stabilised zirconium dioxide exhibits high resistance to thermal shock and erosion. It has low thermal expansion and non-wetting properties. Crucibles made from this material act as fire-resistant and insulating components. They are designed to achieve a clean melt process at temperatures above 1 900°C and are produced for melting superalloys and noble metals. They offer chemical inertness, temperature cycling resistance up to 2 200°C, and corrosion resistance against acids and alkalis.
