Present technological developments are making more extensive use of liquid metals as heat‐transfer agents. Their stable and relatively noncorrosive character makes them especially adaptable for high‐temperature applications. The compatibility of various liquid metals with refractories has been investigated in the past over a temperature range up to several hundred degrees centigrade. To extend this information to much higher temperatures, corrosion experiments were carried out at North American Aviation utilizing liquid sodium, tin, and bismuth. Tests were conducted in the range 800° to 1500°C. using molybdenum, tantalum, tungsten, graphite, alumina, zirconia, and other materials. The experimental apparatus and procedures employed in conducting both static and dynamic tests are described and significant results are summarized.
