ABSTRACT:
The invention provides an improved method for preparing fired ceramic oxide material. A ceramic oxide powder is dispersed in an aqueous solution containing a dispersant having as an active ingredient a dissolved salt of an anionic polymer formed from maleic acid, maleic acid anhydride, or fumaric acid. The slurry containing the dispersed ceramic oxide powder is spray-dried, compressed while substantially dry, and heated to produce a fired ceramic material. Ceramic materials having relatively higher density and strength can be produced by the method.
