Abstract
Molar volumes in the liquid state and melting points of several rare earth chlorides RCl3 (R = La, Pr, Nd, Gd, Dy, and Y) have been measured by dilatometry and DTA. respectively. The volume changes on melting of these chlorides were evaluated on the basis of these result and available crystal structure data. The volume increase on melting of the hexagonal chlorides from LaCl3 to GdCl3 was found to be more than 20%. On the other hand, the volume changes of the monoclinic DyCl3 and YCl3 were less than 1%.Keywords
