Title	Pressure dependence of the thermal conductivity of pyrophyllite to 40 kbar
BYU Creator	Chen, Wei Decker, Daniel L.
Keywords	pressure dependence; thermal conductivity; pyrophyllite; temperature distribution; anisotropic thermal conductivities
Description/Abstract	A mathematical model for calculating the temperature distribution as a function of power delivered to a line source and the thermal conductivity of the surrounding medium in the pressure cell of a cubic-anvil press was derived. The model will handle anisotropic thermal conductivities. A simple sample assembly consisting of a line source and two or three thermocouple junctions is described. A comparison of measured to calculated temperatures yields the thermal conductivity. Thermal conductivity measurements were made on natural pyrophyllite and baked pyrophyllite to 40 kbar. For the natural pyrophyllite the thermal conductivity parallel to the bedding plane at room temperature increased with pressure from 13 to 15 (mcal/s cm K) over the pressure range but for the baked material it decreased with pressure.
