ChemInform Abstract: THERMODYNAMIC PROPERTIES OF GERMANIUM‐MANGANESE MOLTEN ALLOYS

High temperature calorimetric examination of enthalpies of mixing in liquid (gadolinium–germanium–manganese) alloys

“…The low temperature D mix H and D mix H Gd results reported in [54] are more negative than those of [49]. The results of [49], measured directly by calorimetric technique, should be considered as the most accurate.…”

“…Such behaviour is observed possibly due to the increasing metallic contribution into the (Ge-Mn) chemical bond at melting. As formation of the liquid (Ge-Mn) alloys is preferred rather than formation of the solid manganese germanides Solid symbols are the literature data: -j-, [49]; -m-, [52]; -r-, [54]; -d-, [51]; %, [50]; -.-, [53]. The standard state is liquid or overcooled liquid Mn.…”

“…[54]. The enthalpy results can be divided into a low temperature ones measured from T = (1274 to 1300) K [49,50,54] and a high temperature determined from T = (1550 to 1840) K [51][52][53]. The results for the integral enthalpy of mixing and the partial enthalpy of mixing for manganese are compared on figures 2 and 3, respectively.…”

“…The enthalpies of mixing in the liquid (Ge-Mn) alloys have been studied by calorimetry [49][50][51][52][53] and by e.m.f. [54]. The enthalpy results can be divided into a low temperature ones measured from T = (1274 to 1300) K [49,50,54] and a high temperature determined from T = (1550 to 1840) K [51][52][53].…”
