CALCULATIONAL AND EXPERIMENTAL INVESTIGATION INTO THE THERMAL CONDUCTIVITY OF MATERIALS OF CERAMIC CASTING MOLDS. I. EXPERIMENT

The authors have conducted an experimental investigation into the thermal conductivity of materials of ceramic molds for investment casting of heat-resistant alloys. The general characteristic of the methods and equipment used to measure the thermal conductivity of such materials has been given. Results of measuring the thermal conductivity of a number of materials with powders of a course alumina aggregate and of fi ne alimuna, mullite, and zircon aggregates in the range of temperatures from 20 to 1700^o C have been given.
