摘要：This work presents results about the enstatite (MgSiO3) carbonation reaction; which synthesized by starting from the calcination the rough clay coming from a tertiary formation located at the East of the average Atlas (Morocco) at 1000°C. The carbonate of the magnesium (MgCO3) formed after the tender of the sample to a flow of pure CO2 during 15 min in the normal conditions of temperature and pressure. The appearance of magnesite (MgCO3) in diffraction of x-rays is justified by the dissolution of the enstatite was caused by the current of carbonic gas; this indicates that the mineral was reacted to form carbonate of magnesium (magnesite), The analysis of the Raman one was used to supplement the results of XRD, A peak can be observed in the curves (TGA and DTA) between 530 ºC and 600 ºC which is in connection with the decomposition of carbonate; the actual loss of the weight is roughly 18%.
