Abstract
Aqueous ceramic slurries suitable for use in the forming of sintered ceramic bodies are formed by combining a) ceramic particles, b) an aqueous polymer emulsion containing an ethylene/vinyl acetate polymer, and c) water. The slurry is dried to form a free flowing powder which is then dry pressed to form a shape. The shape is then fired to remove the polymer and to sinter the ceramic particles thereby forming the sintered ceramic body. These binder systems do not require the use of organic solvents. The binder systems provide improved formability and green strength.
