Abstract:
This work presents the detailed joint study of temperature dependences of thermal expansion and heat capacity of solid beryllium. It is shown that, as for the earlier studied solid bodies, within the limits of experimental and statistical errors, the heat capacity C(T) and the temperature coefficient of volume expansion β(T) in the entire range of the HCP-phase of metal are in a pronounced correlation β(C) that has a typical (as earlier) “bilinear” form consisting of two smoothly conjugate linear sections with the up-fracture hitting the classical Dulong and Petit heat capacity limit 3R. The consistent values of the heat capacity obtained and the thermal expansion are tabulated and an estimate of the temperature dependence of the Grüneisen differential parameter γ′∼(∂β/∂C) is given.
