Abstract
The solubility of aluminium orthophosphate in cryolite melts was determined. Part of the binary phase diagram of the system Na3AlF6–AlPO4 was investigated. The eutectic point was determined to be at 43.7 mass% (or 57.2 mol%) AlPO4 and (696 ± 1) °C. It is suggested that in pure molten cryolite melts the orthophosphate ion dissociates partly into a metaphosphate ion and an oxide ion.
