ZrO 2 -Y 2 O 3 -CuO powders were prepared by coprecipitation method. The effects of CuO content and calcining temperature on phase structure, grain size and lattice parameters were studied. The dopants CuO inhibited the increase of crystallite size and made the lattice parameter decrease. The result
In compositions having ZrO2/Y203 = (74.25-71.25)/(0.75-3.75) (mol % ratio) with 25 mol % AI203, metastable t-Zr02 solid solutions crystallize at ~ 780 ~ to ~ 860 ~ from amorphous materials prepared by the simultaneous hydrolysis of zirconium, yttrium and aluminium acetylacetonates. Hot isostatic pre
