Density and thermal expansion of silver in the solid and liquid states

Abstract

Abstract Density and thermal expansion of pure silver are investigated using a gamma-ray attenuation technique in the temperature range of 293–1631 K of solid and liquid states. The relative density change of silver during the solid–melt phase transition is directly measured. The approximation dependences for the density are constructed and the data of this work are compared with the results of other authors. Tables of temperature dependences of the volumetric properties of silver are developed over the entire measurement interval and their errors are estimated.
