Abstract: A polymeric binder for ceramic materials is provided. The polymeric binder has a temperature range for pyrolysis which is broader than that for polymeric binders conventionally used in ceramic materials. The broader pyrolysis range provides for gradual removal of the binder when a ceramic part containing the binder is heated. Gradual removal of the binder minimizes the formation of voids and cracking in the ceramic part. Voids or cracking can lead to defects in the part, and destruction of the part may occur during removal if a polymeric binder used in the part is rapidly decomposed into gases. Therefore the polymeric binder of the present invention provides for ceramic parts with fewer defects and less chance of destruction than occurs with polymeric binders conventionally used in ceramic parts.
