RESEARCH ON SYNTHESIS OF ZEOLITES FROM NATURAL MINERAL MATERIALS

Zeolites,as molecular sieves,have many uses,due to their excellent properties,The future is expansive to use natural mineral materials to cheaply synthesize zeolites.This article summarizes it and its technique,generalizing its technique as materials pretreatment,silicic-aluminuous precursors making,silicic-aluminous gel making,hydrothermal crystallizing synthesis,and subsequent treatment.And the article points out the research on crystallizing synthesis mechanism should be study deeply.
