Abstract

Clays obtained from South Africa were used as feedstock materials for the synthesis of zeolites. The conventional alkaline hydrothermal treatment of the starting material (90. °C for 8. h) was preceded by a fusion step (550. °C for 1.5. h) to improve the solubility of aluminium and silicon. Various characterization techniques such as X-ray diffraction (XRD), X-ray fluorescence (XRF), scanning electron microscopy (SEM) and Fourier transform infrared (FTIR) spectroscopy were employed to probe the properties of the as-received clays as well as the resulting zeolitic phase. The synthesized zeolite X and hydroxy-sodalite were of high crystalline quality hence making clay materials a cheaper alternative for producing high quality zeolites.
