Description

Five different samples of esmectites clays were studied for cordierite formation. These clays were treated with salt solutions and calcined at 1000 to 1300 sup(0)C for 1 hour. The synthetic products obtained were characterized by X-ray diffraction. The results show that cordierite can be obtained by this process, but purity depends upon the used clay. High quantities of Fe2O3 were observed and the brown smectite clay has the closest composition to the theoretical cordierite. (author)
