Abstract
A method for improving the properties of ceramic green bodies is provided. In particular, ceramic green bodies having improved green strength are provided. Incorporating certain acid-containing polymers as binders at a level of at least about 1 to about 15, preferably at least about 3 to about 10 percent by weight based on the weight of ceramic particles improves the green strength of the resulting ceramic green bodies.
Claims6
A machinable ceramic green body comprising;
- (a) ceramic particles;
- and
- (b) one or more binders at a level of from about I to about 15 percent by weight based on the ceramic particles;
- wherein the one or more binders are selected from the group consisting of polymers comprising, as polymerized units, at least 40 percent by weight of one or more monoethylenically unsaturated acids, and salts thereof selected from the group consisting of monoethylenically unsaturated carboxylic acids, and salts thereof and from 0 to about 60 percent by weight of one or more monoethylenically unsaturated acid-free monomers.
