摘要： 热分析法研究了BeSO4-Al2(SO4)3-Na2SO4三元熔盐体系的状态图。体系中存在三元转熔(包晶)点P,温度490℃,组成为BeSO418.8Wt%,Al2(SO4)315.0%,Na2SO466.2%;三元低共熔(共晶)点E1,温度为476℃,组成为BeSO420.0%,Al2(SO4)311.2,%,Na2SO468.8%。另一低共熔点E2温度为595℃,组成未能确定。体系中无三元化合物生成。

Abstract: Astudy has been made of ternary salt system BeSO4-Al2(SO4)3-Na2SO4 by the thermal analysis method. A ternary peritectic point containing BeSO4 18.8 Wt%, Al2(SO4)3 15.0%, Na2O4 66.2%, melting at 490℃and a ternary eutectic point containing BeSO4 20.0%, Al2(SO4)3 11.2%, Na2SO4 68.8%, melting at 475℃, were found in this system. The composition of the other ternary eutectic point melting at 595℃has not been exactly determined. No evidence was found about any ternary compound existing in the system.
