Double-thermocouple experiments were carried out at 10 kbar in a 1.27 cm (1/2 in.) piston-cylinder apparatus to map the thermal gradient and locate the peak temperature of a CaF2-graphite furnace assembly over the temperature interval 900–1500 8C. An unexpected but reproducible result was that the thermal peak is displaced upward significantly (toward the steel base plug) from the vertical center of the graphite heater tubes. The hot spot of our assembly, defined as the region no more than 10… CONTINUE READING
