Abstract
Heat contents above 298.16°K of two samples of electrolytic manganese were determined from room temperature to about 1440°K. From these data three transitions occurring at 1000±2°, 1374±5°, and 1410±5°K with heat effects of 535, 545, and 430 calories per gram‐atom, respectively, were observed. Smooth curve values at 100° intervals and corresponding entropies are given as well as heat content and specific heat equations for the four modifications of manganese. A specific heat equation for γ‐manganese was derived for the temperature range 298–1374°K from low temperature and high temperature thermal data; and corresponding heat contents and entropies above 298.16° for γ‐manganese were calculated.
