引言某些特定组成的卤化银单晶或多晶电极已用于卤素离子的浓度测量(1.2),由于纯卤化银晶格的本征缺陷浓度甚低,其室温电导率在10~(-4)～10~(-7)Sm~(-1)之间,影响离子选择电极的测量精度。为了提高电导率,通常采用引入掺杂组分的方法,制备复相混合物、固溶体 Introduction Certain silver halide single crystal or polycrystalline electrodes of specific composition have been used for the concentration measurement of halogen ions (1.2). Since the intrinsic defect concentration of the pure silver halide lattice is very low, its room temperature conductivity is between 10 and (-4) ) ~ 10 ~ (-7) Sm ~ (-1), which affects the measurement accuracy of ion selective electrode. In order to increase the conductivity, a method of introducing a doping component is usually adopted to prepare a complex mixture, a solid solution
