A Study on Pretreatment of Brucite for Mineral Carbonation

Weon‐Kyung Choi, Seung-Hvun Moon, Tae-Hwan Cho, Jae-Keun Lee

Abstract

Pretreatment procedure was investigated into brucite powders for mineral carbonation materials. Higher magnesium content was found from brucite powders and weight loss due to hydroxy group(-OH) elimination, explained by FT-IR spectra, was found after pretreatment. X-ray diffraction results showed that the crystallographic changing of brucite into magnesium oxides during pretreatment. XPS core spectra also showed chemical transformation of magnesium ingredient from hydroxides to oxide.
