ABSTRACT:
The present invention relates to improved investment powders for use in making improved investment molds for casting metals, and the use of such molds with vacuum and/or either conventional, convection conduction or microwave heating apparatus, to rapidly eliminate water, wax and residual carbon from the mold cavities at temperatures lower than the casting temperature range of the mold at the time of casting.
