Transport numbers in the molten system NaF–KF–AlF3 (Al2O3, CaF2) were investigated by the Hittorf method. It was confirmed that in molten cryolite, Na3AlF6, 1,010 °C, the current is transported almost exclusively by the Na+ cations (t(Na+) = 0.99). When AlF3 was added to a Na3AlF6 melt, the transport number of sodium cations decreased to 0.74 at the composition corresponding to NaAlF4. In molten K...
Solubility of lanthanum oxide was measured by thermal analysis. The solubility in alkali cryolites is rather high, because of chemical reactions between lanthanum oxide and cryolites. In Li 3 AlF 6 –La 2 O 3 , alumina precipitates, in the other systems the mixed oxide LaAlO 3 is formed. In La 2 O 3 –Li 3 AlF 6 the eutectic point...
