Abstract
The density and thermal expansion of the melt and high-temperature sol id phase of YbF3 were studied by a gamma attenuation method. Volume ch anges on melting and on polymorphic transformation were measured. The density and volume coefficient of the thermal expansion of the liquid at the melting point are equal to 6284 kg m(-3) and 14.7x10(-5) K-1. R elative density changes on melting and on solid-solid transition are e qual to 2.6% and 16.6%, respectively. (C) 1997 Elsevier Science S.A.
