Paramagnetic Fe3+ centers on the surface of kaolinite particles

A study proposes a new interpretation of the electron paramagnetic resonance (EPR) spectra that are typical for kaolinite. Data indicate localization of Fe3+ cations in surface layers of kaolinite particles affects the characteristics of the surface signicantly and activates the essential technologi...

Description
Summary:A study proposes a new interpretation of the electron paramagnetic resonance (EPR) spectra that are typical for kaolinite. Data indicate localization of Fe3+ cations in surface layers of kaolinite particles affects the characteristics of the surface signicantly and activates the essential technological properties of this mineral.
