摘　　要：报道了水热静态晶化法制备超微ＮａＡ、八面沸石的方法。系统地研究了制备条件对沸石粒度的影响。实验中发现原料配比、盐效应、陈化和晶化等是超微粒沸石合成的关键因素。Ｘ射线小角衍射和扫描电镜分析表明，ＮａＡ沸石平均粒度为６２ｎｍ，八面沸石平均粒度为７６ｎｍ。Report on the preparation of ultramicron powder zeolite NaA and Faujasite using static state hydrotherm techniques The influence of the synthetic conditions on the particle size of zeolite are disussed systematically It has been found by the experiments that crude material ratio,salt effect,ageing and crystallization are all critical factors in the synthesis of ultamicron powder zeolits,the experimental data of diffraction of X-rays and scanning electron microscopy show that the particle size of zeolites NaA is 62 nm,and the Faujasite is 76 nm
