“…It is important to note that the simultaneous preparation of strontium and calcium fluorides has resulted in the formation of the mixture of slightly contaminated individual CaF 2 and SrF 2 , respectively, whereas the use of the other synthetic techniques, such as melting [72], co-precipitation from aqueous solutions [28], or mechanochemical synthesis [73], resulted in continuous Ca 1−x Sr x F 2 solid solution. However, in accordance with the third law of thermodynamics [24], all solid solutions must decompose under cooling, and the lack of such decomposition unequivocally indicates a non-equilibrium state of the prepared specimen.…”

The preparation of NaLnF 4 complexes, LnF 3 (Ln = La, Ce, Y) rare earth binary fluorides, CaF 2 and SrF 2 alkali earth fluorides, as well as mixtures of these compounds from their nitrates dissolved in molten NaNO 3 has been studied in order to select the ideal solvent for fluoride synthesis by spontaneous crystallization from flux. Sodium fluoride (NaF) was used as a fluorinating agent. The results of our experiments have confirmed that NaNO 3 melt is one of the most promising media for precipitating said inorganic fluoride materials within a broad temperature range (300-500 • C). Also, in contrast with precipitation/co-precipitation from aqueous solutions, our syntheses have resulted in obtaining equilibrium phases only.

“…Difluorides with fluorite structure MF 2 , M = Ca, Sr, Ba, Pb, Cd are of particular importance [5][6][7][8][9][10]. Solid solutions of rare earth elements in fluorite matrices, as well as MF 2 -M'F 2 systems, are promising materials for photonics and electrochemical devices [1,[11][12][13][14][15][16][17].…”
