文摘
Solubility was measured for Mg(NO3)2–Ln(NO3)3 (Ln = La, Ce, Pr)–HNO3–H2O (∼21%) + H2O systems at T = 298.15 K. The corresponding phase diagrams were plotted. Three new solid phase compounds 3Mg(NO3)2·2Ln(NO3)3·24H2O (Ln = La, Ce, Pr) were characterized. ΔfHθm for three new solid phase compounds were determined.
