2. 1976.6 1891.9 2013.7 established the capsule is dropped into a container filled with a fluid with which the capsule and the sample material can exchange thermal energy. Based on the i n i t i a l temperatures and the final temperature the heat balance permits the calculation of the total heat content of the capsule and the sample a t the initial temperature. The important features of drop calorimetry are that a l l processes s t a r t from and end in steady atate conditions i.e., rate effects are completely absent and no heat transfer effects interfere with temperature measurements. The data are not obtained from a continuous test but from individual and distinct test points, and the materials property, i.e., the total heat content, is derived from a number of measurements, three temperatures, three weights, the materials property of the capsule, and the evaluation of thermal losses in the apparatus.
3. The ternary eutectic 64 LiF - 30 #gF2 - 6 KF was also tested in a Differential Scanning Calorimeter (Perkin-Elmer 0%-2). The determination of the thermal energy content of the material as a function of temperature is based on a completely dif-793.5 jigram 63" (108°F I
