Incongruent dissolution of chromite in lithium tetraborate flux

摘要

During lithium tetraborate fluxing, chromite undergoes incongruent dissolution, in which high proportions of aluminium, magnesium and titanium are dissolved in the flux while some iron remains behind in a residual chromium-rich phase. Increasing the time and flux/sample ratio improve the dissolution of chromite. Errors in XRF analysis due to incomplete dissolution of chromite in lithium tetraborate flux will have the largest effects for chromium and lesser, although still serious, effects for iron.
