    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.

    Abstract: This invention is a method of increasing the amount of retention of deposited starch and pigment on fibers in broke liquid which consists of adding to said liquid a combination dosage of a DMA-epichlorohydrin polymer together with a second polymer consisting of acrylamide/acrylate. Such a polymer may be anionic, such as an acrylamide/sodium acrylate 5% or 30% acrylic acid, or it may be cationic, such as acrylamide/dimethylamino ethyl methacrylate dimethyl sulfate quaternary. The polymers may be applied to the broke directly and preferably in the form of an inverted water-in-oil emulsion. The dosage based on dry weight of starch (T) ranges from 2-35 lbs/T of the DMA-epichlorohydrin polymer product (48% polymer, 0.96-16.8 lbs/T polymer) and 0.5-8 lbs/T based on the second polymer product (28% polymer, 0.14-2.24 lbs/T polymer) selected from the group consisting of copolymers of acrylamide/acrylic acid; copolymers of acrylamide/alkali metal acrylate (e.g., sodium acrylate); copolymers of acrylamide/dimethylamino ethyl methacrylate dimethyl sulfate quaternary (DMAEM.DMS quat).
