摘　　要：Aluminosilicate zeolite ECR-1 was successfully obtained under hydrothermal condition at 100 ℃ by hydrothermal phase transition of zeolite Y in the absence of organic template.When n(Na2O)/n(SiO2)ratio in the starting aluminosilicate gel[n(SiO2)∶n(Al2O3)∶n(Na2O)∶n(H2O)=10∶1.0∶2.5—3.3∶200] was 0.33,the phase transition from zeolite Y to zeolite P occurred.However,when the n(Na2O)/n(SiO2)ratio was 0.25,zeolite Y was converted into zeolite ECR-1.In this case,zeolite Y was served as nutrient for the crystallization of zeolite ECR-1.Aluminosilicate zeolite ECR-1 was successfully obtained under hydrothermal condition at 100℃ by hydrothermal phase transition of zeolite Y in the absence of organic template. When n（ Na2O）/n（ SiO2） ratio in the starting aluminosilicate gel [ n （ SiO2 ） ： n （ Al2O3 ） ： n （ Na2O） ： n （ H2O） = 10： 1.0： 2.5--3.3 ： 200 ] was 0. 33, the phase transition from zeolite Y to zeolite P occurred. However, when the n（Na2O）/n（SiO2） ratio was 0.25, zeolite Y was converted into zeolite ECR-1. In this case, zeolite Y was served as nutrient for the crystallization of zeolite ECR-1.
