STUDY OF SOME CLINOPTILOLITE,HEULANDITES AND MORDENITES IN CHINA

This paper introduced the results of preliminary studies on clinoptilol’tes,heulan-dites and mordenites found in China.These samples were centrifugally seperated by heavy liquid,and the pure zeolites were obtained.Then,the pure zeolites were chemically analyzed by wet methodsi and their cell dimensions were determined.It is suggested that clinoptilolites in China commonly have relatively high contents of alkaline earth metals and most of them can be ascribed to Ca-type clinoptilolite.The water contained in clinoptilolite and heulandlite depends on the ratio of Si/Al as well as on the amount of alkaline earth metals.The cell dimensions of all the clinoptilolite and heulandite samples show little variation,especially along the c axis.
