摘要：
A process of producing a ceramic powder including providing a plurality of precursor materials in solution, wherein each of the plurality of precursor materials in solution further comprises at least one constituent ionic species of a ceramic powder, combining the plurality of precursor materials in solution with an onium dicarboxylate precipitant solution to cause co-precipitation of the ceramic powder precursor in a combined solution; and separating the ceramic powder precursor from the combined solution. The process may further include calcining the ceramic powder precursor.
