Abstract
Polyvinyl alcohol copolymers are used as binder in an aqueous ceramic particle slurry for injection molding green ceramic bodies. The slurry is dried to form a coated powder which is then heated and injection molded into a desired shape. The molded shape is then fired to remove the binder and produce a dense ceramic part. The dense parts do not show any knit lines from the injection molding step.
