Zirconia Crucibles (ZrO2) offer three advantages over their alumina crucible counterparts: they are more refractory, having a melting point some 500oC above alumina. They are readily machined and give a high quality surface finish and are a useful oxygen anion conductor for use in sensors and fuel cells. However, they are considerably more expensive than alumina.
Zirconia has the complication of being metastable and needs to be stabilised before it can be put to use. The addition of small quantities of stabilising oxides such as CaO, MgO and best of all Y2O3 allow the high temperature cubic phase to stabilise itself. Partially stabilised zirconia can also be used as a toughening agent in alumina.
Almath is an ISO 9001:2015 certified technical ceramics manufacturer based in Newmarket, Suffolk, United Kingdom.
