Abstract:

The double clamshell arc imaging system has been successfully applied in a practical arrangement for physical property measurements. Thermal ex pansion measurements of alumina and zircon have been made to 1950 K 1670 C. An inflection in slope of the thermal expansion of zircon was observed at 1570 K indicating a possible phase transition previously unreported. Simple modifications coating of mirrors will provide higher temperatures calculated at 2260 K. Electrical property measurements can be made in the fieldfree environment. Author
