2353.     ---------------.  [NAESER, G.]  [Specific Heat of the Iron Carbide Fe3C.]  Mitt. Kaiser-Wilhelm-Inst. Eisenforsch. Düsseldorf, vol. 16, 1934, pp. 207-210; Chem. Abs., vol. 29, 1935, p. 2434.

        Heat contents of pure crystalline Fe₃C were measured between –190° and +770°, and average and true specific heats were calculated; the values are tabulated.  The rule of additivity of atomic heats does not hold good for cementite.  Heat of reaction of the magnetic transformation is about 1.5 cal. per gm.  18 rfs.
