Abstract

According to E. Kordes and G. Nolte (1969), the dissocn. of molten Na2W2O7 was assumed to give 2Na+, WO42-, and WO3 whereas R. J. H. Gelsing et al. (1966) assumed a dissocn. into Na+ and a mixt. contg. chains of WO4 tetrahedra (WO42-, W2O72-, W3O102- etc.). It was demonstrated that the dissocn. scheme proposed by Gelsing et al. explained well the cryometric results of Kordes and Nolte. Regarding the data of surface tension measurements from Gossink and Stevels, the dissocn. scheme according to Gelsing et al. is more probable than that proposed by Kordes and Nolte.
