Through two-step hydrothermal method,zeolite NaX had been synthesized from quartz sand as silica source. The effects of synthesis temperature,reaction time,concentration of alkali,Si-Al ratio on the synthesis of results were investigated. The sample of zeolite had been characterized via X-ray diffraction,TG-DTA,. And SEM. The characterization results showed that quartz as silica source,the zeolite NaX with high crystallinity can be synthesized.
