Preparation of pure and stabilizer (MgO,CeO2)-added ZrO2 powders and their crystallization behaviour

Amorphous precursor materials for pure and MgO and CeO" containing Zr02 were prepared via alkoxide hydrolysis, gel formation and solution spray drying techniques. The crystallization behaviour of such precursor powders was studied by calcining them at 700°, 1000° and noocc. It was shown that the initial product(s) of crystallization, as well as the conversion product(s) at higher temperatures could depend significantly not only on the overall mode of precursor preparation, but also on subtle differences within the same preparative technique
