STUDY OF SODIUM SULFATE BEHAVIOUR IN THE SYSTEM OF SODIUM-ALUMINIUM FLUORIDES

摘要

Behaviour of S impurities in cryolite melt is described. Important regularities, such as absence of interaction between Na_3AlF_6 and Na_2SO_4; lowering of cryolite melting temperature and its dependence on cryolite relationship, are established via precise methods of physical-chemical analysis.
