大多数碘酸盐具有良好的电光、非线性光学和压电性能,因此,人们对碘酸盐的结构和性能进行了广泛的研究,已测定了锂、钠、钾、铷等碱金属碘酸盐的晶体结构,并观察到CsIO_3粉末也具有较强的倍频效应.由于难以生长单晶和结构上呈现赝立方对称性,至今人们还未确定出其晶体结构.因此,碱金属碘酸盐随碱金属原子半径的增大,其晶体结构类型发生变化的规律并没有完全阐明,解决 CsIO_3的晶体结构,对了解碱金属碘酸盐结构类型的变化具有一定的意义.
Most iodates have good electro-optical, non-linear optical and piezoelectric properties, and as a result, extensive studies have been conducted on the structure and properties of iodate. The iodine acid has been determined for lithium, sodium, potassium, Salt crystal structure, and also observed CsIO_3 powder also has a strong frequency-doubling effect.Due to the difficulty of growing single crystal and the structure of the pseudo-cubic symmetry, so far it has not yet been determined its crystal structure, therefore, alkali metal iodate With the increase of the atomic radius of alkali metal, the regularity of the change of its crystal structure type is not completely elucidated. Solving the crystal structure of CsIO_3 is of certain significance for understanding the change of the structure type of alkali metal iodate.
