Preparation of Zeolite A from Natural Stellerite

Article Preview

Abstract:

Zeolite A was prepared from natural stellerite under hydrothermal conditions.The experiments were carried at different crystallization temperatures and times,the experimental results and synthetical factors were analyzed and researched. The end products have been characterized by using FT–IR, X–ray diffraction (XRD) and scanning electron microscopy (SEM). The results indicate that zeolite A was synthesized on the condition of the crystallization temperature at 90~100°C and the crystallization time for 6 hours with 15% hydrochloric acid of stellerite modifying,according to certain proportion of stellerite.
