Description
Summary:The phase diagrams of the NaBO 2 -NaCl-Na 2 CO 3 , NaBO 2 -Na 2 CO 3 -Na 2 MoO 4 , NaBO 2 - Na 2 CO 3 -Na 2 WO 4 , and NaBO 2 -NaCl-Na 2 WO 4 ternary systems were studied by a calculation-experimental method and differential thermal analysis. The coordinates of ternary eutectics were determined: E 1 : 612°C, 16 mol % NaBO 2 , 42 mol % NaCl, and 42 mol % Na 2 CO 3 ; E 2 : 568°C, 12 mol % NaBO 2 , 28 mol % Na 2 CO 3 , and 60 mol % Na 2 MoO 4 ; E 3 : 575°C, 12 mol % NaBO 2 , 32 mol % Na 2 CO 3 , and 56 mol % Na 2 WO 4 ; E 4 : 628°C, 8 mol % NaBO 2 , 20 mol % NaCl, and 72 mol % Na 2 WO 4 ; and E 5 : 655°C, 9 mol % NaBO 2 , 53 mol % NaCl, and 38 mol % Na 2 WO 4 .
