Cubic zirconias stabilized by various additive oxides have been obtained by mechanical alloying using high‐energy ball‐milling. Starting materials are powders of monoclinic zirconia mixed with magnesia, calcia, or yttria. Solid‐state reaction is induced by ball‐milling and, under given experimental conditions, a single phase consisting of cubic‐zirconia nanocrystals is prepared from constituent oxides. Energy dispersive analyses in electron microscopy on ball‐milled powders confirm that cubic zirconias have the composition corresponding to that of starting powders.
