ABSTRACT:
A composition suitable for use as a binder of ceramic materials and a method for preparing a ceramic material which provides relatively greater green ceramic strength is disclosed. The improved binder contains substantially hydrolyzed copolymer made from monomers having ester or amide functional groups, poly(vinyl amine), poly(vinyl formamide) or a copolymer of vinyl alcohol and vinyl amine. The binder is combined with an aqueous solution containing a ceramic powder to make a slurry, and the slurry is subsequently spray dried, pressed and heated to make a ceramic.
