摘要：

Specific heat of (NH4)3H(SO4)2 was measured in a temperature range 90K≲T≲440 K covering the four phase transitions. The transition entropies were estimated to be Δ SI–II=2.5 ±0.2, ΔS II–III=2.10 ±0.08, ΔSIII–IV=0.51±0.03 and ΔSIV–V=0.53±0.03 in the units of cal ·mol-1·deg-1 for the I–II, II–III, III–IV and IV–V phase transitions, respectively. © 1979, THE PHYSICAL SOCIETY OF JAPAN.
