ABSTRACT:
Individual mold sections are injection molded from a slurry of ceramic particles and a binder. Each of the green individual mold sections is low temperature fired to remove therefrom a major portion of the binder while leaving therein a minor portion of the binder sufficient to afford structural strength thereto, and the individual mold sections are assembled together to form a mold. Finally the mold is high temperature fired to complete removal of the binder.
