ABSTRACT:
A method for producing materials having a high purity, which comprises forming an oxidation reaction product of a parent metal and an oxygen-containing vapor-phase oxidant, comminuting the resulting ceramic body and leaching any non-oxidation reaction product and/or corresponding filler materials therefrom, and recovering said substantially pure materials.
