Abstract

The density of ErF3 was measured with a gamma densimeter at temperatures from below the α–β phase transition to above the melting point. The density and volume expansivity of liquid ErF3 just above the melting point were found to be 6092 ± 30 kg/m3 and (15.1 ± 0.5) × 10–5 K–1. The relative changes in density accompanying the melting and polymorphic transformation of ErF3 are 0.75 ± 0.1 and 16.9 ± 1.3%, respectively. The results, together with earlier data, were used to reveal general trends in the variation of thermal properties across the ErF3 to LuF3 series.
