Creators

Description

A method is described of preparing a sinterable metal oxide ceramic precursor powder, comprising: mixing an aqueous solution of polyvalent metal cations of one or more metals taken from the group consisting of yttrium and zirconium with an aqueous solution of ammonium polyacrylate to form a metal polyacrylate precipitate, separating the precipitate from the aqueous mother liquid, burning out the organic portion of the precipitate, and calcining the ash to form a sinterable ceramic percursor powder
