In-Sr (Indium-Strontium) H. Okamoto The assessed In-Sr phase diagram is based on the experimental studies of [ 66Bru]. The original diagram of [66Bru] showed In2Sr3, which was determined metallographically, instead of In3Sr5, which was determined later by structural analysis [78Bru]. In2Sr and InSr3 melt congruently at 930 and 558 C, respectively [66Bru]. Formerly, solid Sr was believed to have three allotropic forms, with transition temperatures at 605 and 213 C [King2], and [66Bru] observed a transition of Sr at ~610 C. The disagreement regarding transition temperatures of Sr indicates that the thermal analysis data of [66Bru] may have been influenced by impure Sr. Because no other data were available, the temperatures given by [66Bru] are accepted as reported. [69Das] predicted that the In-Sr system shows immiscibility in the liquid state. However, no such trend was observed experimentally. 64Ian: A. Iandelli, Z. Anorg.
