Abstract
The density changes during melting and the thermal expansion coefficie nts of the LiF YF3, and LiYF4 melts were measured over a wide temperat ure range (from the melting point to 1300-2300 K) by exposing samples to a narrow gamma-ray beam. The melting of yttrium fluoride is accompa nied by extremely small volume changes, indicative that the melt and t he crystal differ very little in short-range order.
