Abstract
Thermal transformations in calcium iodate were studied by differential scanning calorimetry in the temperature range of 300–973 K. The process was found to proceed by the scheme: Ca(IO3)2∙H2O → Ca(IO3)2 → Ca5(IO6)2 + I2 + 9O2. Calculated kinetic parameters adequately described experiment. X-ray diffraction patterns of the intermediate products formed at 523, 723, and 873 K well agreed with the available literature data.

碘酸钙的热解：动力学参数
摘要
通过差示扫描量热法在300–973 K的温度范围内研究了碘酸钙的热转化。发现该过程按以下方案进行：Ca（IO 3）2 ∙H 2 O→Ca（IO 3）2 →Ca 5（IO 6）2 + I 2 + 9O 2。计算的动力学参数充分描述了实验。在523、723和873 K处形成的中间产物的X射线衍射图与现有文献数据完全吻合。
