摘要
用等温法测定了25℃K2SO4-(NH4)2SO4-H2O四元体系相平衡的数据,并依据湿渣法与X射线衍射相结合的方法对平衡固相组成进行了鉴定,发现该三元体系相图存在5个结晶区,分别是硫酸钾、硫酸铵、和硫酸钾与硫酸铵固溶体3个纯固相的结晶区,硫酸钾和硫酸钾与硫酸铵固溶体两个固相共饱结晶区,及硫酸铵和硫酸钾与硫酸铵固溶体两个固相共饱结晶区.
The solubility of the phase equilibrium of three component K2SO4-(NH4)2SO4-H2O system at 25℃ has been measured by isothermal method, the nature of the phase solid was also verified by analyzed moist residues and X ray spectroscopy. It is found that there are five liquid-solid phase region in this three ternary diagram, they are K2SO4, (NH4)2SO4, K(NH4)SO4 three single phase regions respectively, and K2SO4 with K(NH4)SO4, (NH4)2SO4 with K(NH4)SO4 two solid phase regions respectively.
