  • The thermal conductivity of polycrystalline, cubic CuCl has been measured from 100 to 480 K and pressures from 0.5 to 2.7 GPa by a transient hot-wire technique. The heat transport is produced by phonons. The absolute value of the conductivity is low and becomes nearly temperature independent at high temperatures where it is approaching the minimum possible value. The conductivity decreases with increasing pressure; its volume derivative, g, is negative over the whole range studied. This effect is related to the negative Grüneisen parameters, γ, for the transverse-acoustic phonons. Some specific-heat-capacity values were also measured.
