Abstract
The density of ErF3 was measured with a gamma densimeter at temperatures fr om below the alpha-beta phase transition to above the melting point. The de nsity and volume expansivity of liquid ErF3 just above the melting point we re found to be 6092 +/- 30 kg/m(3) and (15.1 +/- 0.5) x 10(-5) K-1. The rel ative changes in density accompanying the melting and polymorphic transform ation 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 var iation of thermal properties across the ErF3 to LuF3 series.
