A novel preparation of calcia fully stabilised zirconia from molten alkali-metal nitrate
Abstract
A novel preparation of cubic calcia stabilised zirconia (CaO–ZrO2) which employs the coprecipitation of the constituents from zirconium oxychloride (ZrO1.22Cl1.56) and calcium nitrate [Ca(NO3)2] with eutectic lithium nitrate-potassium nitrate (LiNO3–KNO3) at around 600 °C is described. The optimisation and advantages of the preparation are discussed.
