Sugawara T.; Akaogi M. (2003)Fusion enthalpies were measured by differential scanning calorimetry (DSC) for mineral mix-tures of eutectic composition in the systems anorthite-diopside (An42Di58, wt%), anorthite-akermanite (An46Ak54), akermanite-diopside ...
-
Kojitani H.; Akaogi M. (1997)High-temperature drop calorimetry in the temperature range of 1398-1785 K was performed for the samples of mixtures of synthetic anorthite (An), diopside (Di), enstatite (En) and forsterite (Fo) with the same compositions ...
