【摘要】 本文用X射线粉末衍射与热学分析等方法对碘酸钡、碘酸锶、碘酸钙、碘酸锌、碘酸镉的相变过程、热稳定性和结构进行了研究。对二价碘酸盐之间形成复盐的可能性也进行了探讨。并讨论了二价碘酸盐水化物的稳定性与阳离子电负性的关系。更多还原

【Abstract】 The phase transitions, thermal stabilities and crystal structures of strontium iodate, barium iodate, calcium iodate, zinc iodate and cadmium iodate have been investigated by means of X-ray powder diffraction and thermal analyses. The possibilities of formation of complex compound between divalent iodates have been studied. The stability of hydrated divalent iodates is expected to be related to the electronegativity of the corresponding cations.更多还原
