Determining Optical Basicity of Molten Chloride Salts for Solar Thermal Applications
… makes pH measurements irrelevant. Alternative basicity metrics, such as optical basicity (OB), are needed to predict corrosion. OB allows for measurement of the Lewis basicity, or the extent of electron donation from ligands in the molten salt, via the nephelauxetic effect of an added probe …

Aspects of the chemistry of titanium dioxide in fused salt solvents
… melts has been obtained from measurements of the optical basicity of M2O + B2O3 (M = Li, Na, K, Rb, Cs) glasses, using Pb(II) as probe ion. The results of these measurements have confirmed that the nature of the alkali metal cation significantly affects the basicity of fused alkali borate …

Investigation of the thermodynamics of iron phosphate melts and stability of iron phosphate glasses: effects of composition and iron redox ratio
… examination of iron phosphate glasses using optical spectroscopy. Absorption near ~476 nm was determined to be predictive of iron valence state, and a deconvolution method is proposed to analyze iron coordination environments. Two models were developed using optical basicity and a …

The influence of inert anode material and electrolyte composition on the electrochemical production of oxygen from molten oxides
… evolution reaction are discussed. Notably, the basicity of the molten aluminosilicate electrolyte was found to greatly influence the rate of oxygen gas evolution as evidenced by the linear dependence of the current density on optical basicity. This is crucial for the design of a full-scale …
