Abstract

Differential pulse voltammetry of Cr⁶⁺/Cr³⁺ in alkali silicates, which has been worked in the previous study (Ref. (11)) was extended to silicate melts containing alkalin earth oxides. The basicity scale of new systems finds more relevant applications to practical slags. As compared at the disilicate composition, the basicity increase in the order of MgO, CaO and Li₂O, BaO, Na₂O, K₂O, Rb₂O, and Cs₂O.
