摘　　要：用福州叶蜡石，在适量补硅的条件下，可合成出Ｙ型沸石产物，用ＸＲＤ进行了表征，其硅铝比为４．１～５．０，每克叶蜡石可制出１．２克产品，对焙烧和合成过程进行了分析和讨论，试验结果表明：叶蜡石可作为合成Ｙ型沸石的廉价原料，有良好的应用前景。Zeolite Y was synthesised from Fuzhou pyrophyllite under condition of adding an amount of Na_2 SiO_3.The products were characterized by XRD.The ratio of SiO_2/Al_2O_3 equals 4.1￣5.0.The per gram pyroaphyllite yield of zeolite Y is 1.2 gram. The process of roast and synthesis were analyzed and discussed. The results of experiments show that the pyrophyllite can act as a kind of low-priced raw material for the synthesis of Zeolite Y and displays good application prospects.
