Young's modulus of elasticity, transverse strength, extensibility, and load resistance were determined at a series of test temperatures on six groups of laboratory‐prepared refractory castables which had ( a ) no heat‐treatment, ( b ) heat‐treatment at 1050°C., and ( c ) heat‐treatment at 1300°C. The data suggested that the alterations in composition that occur with a rise in temperature were related to corresponding changes in modulus of elasticity and strength. The effects of dehydration, conversion of amorphous alumina to γ‐alumina, and silica inversions were evident. The cement content and temperature of operation as well as the heat‐treatment of the castables affected all these mechanical properties to varying degrees.
