“…51,[63][64][65][66] High-temperature heat capacity measurements have been made using a variety of instruments, beginning with traditional drop calorimetry. [67][68][69][70] Adiabatic calorimetry has also been used, 53,55,56,59,71 along with laser flash calorimetry, 60,61,72,73 DSC, [64][65][66]74 and AC calorimetry. 75 However, high-temperature measurements are somewhat rare, in part because of the tendency of phosphides to decompose when heated.…”
