AbstractA method for preparing ceramic particle slurries having controlled rheological properties to allow further processing to ceramic green bodies with improved compaction, green strength and green density is disclosed. Polymer additives containing 0.1 to 20% of acrylic acid and/or methacrylic acid monomer units are especially useful in controlling the viscosity of high solids aqueous slurries of ceramic particles and acting as binders to improve the strength of finished ceramic articles, such as sinks, spas, bathroom fixtures and sanitaryware.
