Structural Order of Clays from Gounioube’s Deposit (Ivory Coast): Study by Electron Paramagnetic Resonance Spectroscopy

Abstract

Cristallinity in kaolin samples from Gounioube’s deposit is studied. For this purpose, the behavior of iron and electronic defects related to irradiation damage in these clays is examined by using Electron Paramagnetic Resonance spectroscopy measurements, which point out the presence of structural defects in these materials. A deep inspection carried out by comparison of raw and bleached samples also confirms poorly cristallized samples kaolinite.
