Lithium metaborate dissolves acidic oxides such as SiO2 and Fe2O3, where the stoichiometric ratio of oxygen to cation, y/x in MxOy, is greater than unity. Lithium tetraborate dissolves basic oxides such as CaO, MgO and other oxides of the alkali metals and alkaline earth metals, where y/x ≤ 1. Most oxides are best dissolved in a mixture of the two lithium borate salts, for spectrochemical analysis.
