Base on the thermodynamic calculation, CsI (s) does not decompose to Cs (s) and I (s) at 600°C, either does not from I2(g), CsO(g), CsO2(g), Cs2O(g), and Cs2O3(g). However during the experiment when CsI(s) is heated above to 200 °C at 1 atm the purple vapor can clearly be obviated. The vapor should be I2(g). It is because the incomplete boing of I- which in the CsI compound is evaporation. In this paper, we are interesting in CsI properties during heating and calculation the Cs-I-O thermodynamic characterizations by the thermodynamic data books. |
