    Among the 21 pseudo-binary systems formed by alkali-metal iodates (including HIO3 and NH4IO3), there are 9 in which compounds can be synthesized in aqueous solutions or by powder-sintering, 6 which are mixtures of the constituents; and the rest of the systems can formed continuous solid solutions. The pseudo-binary systems KIO3-NHJO3, RbIO3 etc. were studied by means of thermal analysis (DTA, TG) and Xray diffraction, and were found to be of continuous solid solutions. With addtion of KIO3 or RbIO3, the phase transition temperature of NH4IO3 is decreased and its decomposition (at the same time burning) temperature is raised; the room temperature phase of NH4IO3 (monoclinic) is transformed gradually into cubic phase with increasing content of KIO3 or RbIO3. Samples in the binary systems with NH4IO3 as a component exhibit good pyroelectric property. In this paper, the stability and the change of lattice parameter with compositions of the solid solutions that were found in alkalimetal iodate binary systems were also discussed.

    碱金属碘酸盐形成的二十一个赝二元系中,六个体系为机械混合物,九个体系是形成化合物的(其中三个是离子化合物),其余六个体系形成连续固溶体。本文对KIO_3-NH_4IO_3,RbIO_3-NH_4IO_4等赝二元系形成的连续固溶体进行了研究。NH_4IO_3中加入KIO_3或RbIO_3时,随加入量增加,NH_4IO_3的相变温度降低而分解燃烧温度升高。同时,NH_4IO_3的室温单斜相则逐渐转变为立方相。含有NH_4IO_3的赝二元系晶体有较突出的热电性。本文还讨论了碱金属碘酸盐赝二元体系中的六个连续固溶体的稳定性及其点阵常数的变化。

    The pseudo-binary system LiIO3-Zn(IO3)2 has been investigated and its phase diag-ram determined by means of X-ray diffraction and DTA, using specimens prepared by solid state powder sintering method. A new phase, the formula of which can be written as LiZn(IO3)3, has been found to exist in single phase within a wide range of composi-tions. It is an ionic conductor and has remarkable SHG effect as determined by the powder method. The lattice paremeters of the compound LiZn(IO3)3 have been determined by a computer programme, using the powder diffraction data. It is found that the compound belongs to orthorhombic system with a = 8.081 A, b = 8.729 A, c = 11.595 A, z = 4.
