Solubility of AlPO4 and NaVO3 in NaF-AlF3 melts
The temperatures of primary crystallization of cryolite in systems NaF-AlF3-AlPO4 and NaF-AlF3-NaVO3 were determined by thermal analysis. The measurements were performed at cryolite ratios (CR) equal to 2.5 and 2 [CR = n(NaF)/n(AlF3)]. It is evident that AlPO4 decreases the temperature of primary crystallization of cryolite more than NaVO3 at both selected cryolite ratios.
