  • Changing the distribution of the thermal couple, a new experimental assembly, which is stable at extremely high temperatures, has been developed for the cubic press.Test experiments showed that at 5 GPa, this new experimental assembly can be stable at 1 600, 1 800 and 2 000 ℃ for more than 48 hours, about 30 h and about 10 h, respectively.Additionally, the temperature gradient in the new experimental assembly is very low:at 1 454 ℃, it is about 27 ℃/mm in the 4 mm long central part of the graphite heater.Long stable duration at extremely high temperatures and low temperature gradient make this new experimetal assembly suitable for the high-pressure experimentation in Geosciences.
