摘要
A thermal change of a tin iodide (SnI2) evaporated film as deposited on a glass substrate has been successfully detected by TG-DTA and evaluated semiquantitatively by DSC in nitrogen and air (heating rate 10°C min−1); the film area was ≈0.5 and ≈ 0.25 cm2 for TG-DTA and DSC, respectively. In nitrogen, a sharp endothermic peak at 317.9°C was interpreted as denoting the melting of SnI2; an endothermic weight loss at 260–420°C was interpreted as the sublimation and evaporation of SnI2. An exothermic weight loss at 180–290°C in air was interpreted as the oxidation reaction proposed in our previous papers [Thermochim. Acta, 232 (1994) 29–36; 232 (1994) 37–45; 243 (1994) 95–100], namely 2SnI2(s) + O2(g)→SnO2(s) + SnI4(g).
