摘要
采用等温溶解平衡法测定了三元水盐体系(NH4)2SO4-NH4NO3-H2O在50℃的溶解度数据,绘制了三元体系相图。结果表明,体系在50℃的相图存在6个区域,即(NH4)2SO4的结晶区、NH4NO3的结晶区、以(NH4)2SO4为主的固溶体结晶区、以NH4NO3为主的固溶体结晶区、以(NH4)2SO4为主的固溶体和以NH4NO3为主的固溶体共同结晶区及不饱和区。
The dissolution data of ternary system （NH4）2SO4-NH4NO3-H2O at 50℃ was measured by isothermal solution equilibrium method. Based on the data, phase diagram of the ternary system was plotted. The result showed that phase diagram of the system existed six regions. The regions were （NH4）2SO4 pure crystalline region, NH4NO3 pure crystalline region, （NH4）2SO4 and NH4NO3 dominated solid solution regions respectively, co-crystalline region of（NH4 ）2SO4 and NH4 NO3 dominated solid solution, and unsaturated region.
