Abstract : Heats and entropies of fusion, and heat content data for CaBr2, SrCl2, BaCl2 and BaBr2, determined by the method of phase-transition drop calorimetry, are reported. Solid-state transitions were confirmed for SrCl2 and BaCl2, and the possible nature and extent of these transitions are examined. An assessment of the phase-transition properties for the alkaline earth halides and nitrates is developed and the results are discussed relative to pre-melting effects and the process of fusion for these salts. For SrCl2, the relatively small value of the melting and pre-melting effects is note-worthy. (Author)
