Vl. Cherginets et al., ON THE SOLUBILITIES OF METAL-OXIDES IN IONIC MELT-2 CSBR-CENTER-DOT-KBR AT 700-DEGREES-C, Electrochimica acta, 41(3), 1996, pp. 463-467
Solubility products of 10 metal oxides MeO in molten eutectic mixture
CsBr-KBr(0.67:0.33) at 700 degrees C have been determined by a potenti
ometric titration technique using a membrane oxygen electrode Pt(O-2)\
ZrO2(Y2O3). Oxide solubilities have been stated to be essentially less
than those for molten chlorides at the same temperature. Dependences
of oxide solubilities in the bromide melt vs. their physical constants
have been found to be similar to those for molten alkaline chlorides.
Decrease of oxide solubility has been connected with the strengthenin
g association of bromide melts as compared with chloride ones.
