Abstract
The density of liquid lithium fluoride and an eutectic mixture of lithium fluoride and sodium fluoride (with a content of 39 mol. % NaF) was measured by the gamma ray method in the temperature range from liquidus to ~1280 K. The obtained results were compared with the available literature data. The study of liquid eutectic LiF - NaF was carried out in a significantly wider temperature range compared to other authors, and the obtained values of the volumetric coefficient of thermal expansion turned out to be the most reliable.
