摘　　要：4A Zeolite has been prepared from Kaolin under low-temperature hydrothermal conditions. The analysis results on the concentration changes of NaOH, SiO2 and Al2O3 in liquid phases as well as the texture, morphology and structure changes of solid phases show that the crystallization process of 4A zeolite roughly comprises three periods: induction of crystal nucleus, crystal growth and steady state transformation.4A Zeolite has been prepared from Kaolin under low-temperature hydrothermal conditions.
