Description
Summary:(ProQuest: ... denotes formulae/symbols omitted.)Temperatures for the primary crystallization of ... system adopted in aluminum electrolysis process were determined by thermal analysis. An empirical equation was derived to describe the liquidus temperatures for the primary crystallization of this multicomponent electrolyte system: ... , where w(AlF3) denotes the mass fraction of excess aluminum fluoride with respect to cryolite. While w(Al2O3) ranges from 2% to 4%, w(LiF), w(KF) and w(CaF2) from 0% to 7%, and the molar ratio of NaF/AlF3 from 2.2 to 3.
