  • Iron in kaolinite with special reference to kaolinite from

    The iron of most of the kaolinites can be divided into a 'structural iron' content, measured by the amount of iron, dissolved at the same rate as aluminium by acid attack, and a 'resistant iron' content, which is concentrated with the residuesCalibration of the internal and external signals appearing at g eff ∼4 in the electron paramagnetic resonance (EPR) spectra of twentyfour kaolinites, has led to the recognition of two types of kaoliniteiron The amount of iron associated with the internal signal (I iron) shows good inverse correlations with parameters used to describe the degree of crystalline perfection in kaoliniteIron in kaolinite: II The relationship between kaoliniteKAOLINITE often occurs in admixture with other minerals (for example, micas and iron oxides) in which iron is a legitimate constituent Because of the difficulties of detection and separation, itSubstitution by Iron in Kaolinite | Nature
