The phase diagram of the isobaric binary system (NaNO3 + RbNO3)

The phase diagram of the isobaric binary system (NaNO 3  + RbNO 3 ) was traced from the results obtained by using simultaneous direct and differential thermal analysis, differential scanning calorimeter, and X-ray diffraction. This phase diagram shows seven invariants: two eutectics, one eutectoid,...

Zusammenfassung:The phase diagram of the isobaric binary system (NaNO 3  + RbNO 3 ) was traced from the results obtained by using simultaneous direct and differential thermal analysis, differential scanning calorimeter, and X-ray diffraction. This phase diagram shows seven invariants: two eutectics, one eutectoid, one peritectic, and three metatectics at (447, 449, 433, 561, 473, 496, and 581) ± 1 K, respectively. A congruently melting intermediate compound, NaRb 2 (NO 3 ) 3 , was also observed. It melts at (451 ± 1) K and has two polymorphic transitions at (437 ± 1) and (443 ± 1) K.
