| description | The present invention relates to impregnated fired ceramic cores for use in investment casting of metallic materials and a method of increasing strength of such cores.
An impregnated fired, porous ceramic core for use in an investment casting shell mold in the casting of molten metals and alloys is strengthened by impregnating the core with an aqueous emulsion of water-insoluble polymer followed by drying to remove the water. |
