【摘要】 用固态粉末烧结法配制样品,用X射线衍射及差热分析等方法研究并测定了LiIO₃-Zn（IO₃）₂赝二元系的相图。该二元系内存在一新相LiZn（IO₃）₃。它有较大的倍频效应,具有离子导电性。用自编的由粉末衍射数据求单斜晶系的点阵参数的计算机程序成功地求出了该化合物的点阵常数。经过进一步修正,确定它属于正交晶系,α=8.08lA,b=8.729A,c=11.595A,z=4。并确定了化合物存在的成分范围和条件。更多还原

【Abstract】 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.更多还原
