Abstract
A method for making essentially crack free large cross section ceramic articles by injection molding techniques comprises the use of from about 0.1 v/o to about 10 v/o fibers with the ceramic injection molding formulation followed by the injection molding, binder removal and densification steps to form an essentially crack free densified large cross section ceramic article. The fibers are softened prior to the onset of densification and incorporated into the ceramic intergranular phase. This process eliminates the component distortion during densification which would have occurred if the fibers remained in the component.
