METHOD FOR PRODUCING SUBSTANTIALLY PURE ALUMINA MATERIAL

A method for producing an alumina of high purity, which comprises forming an oxidation reaction product of an aluminum parent metal and an oxygen-containing vapor-phase oxidant, comminuting the resulting ceramic body, and leaching any non-alumina materials therefrom, and recovering said substantiall...
