摘要
Abstract
Zeolites 4A was prepared successfully by low-temperature hydrothermal synthesis, using cheap Si-al slag as raw materials.The effects of treatment conditions, including reaction components,operating temperature and hydrothermal reaction time were investigated through XRD and SEM.The results illustrate that the optimal synthetic conditions for 4A zeolites and follows: n(SiO2 )/n(A12O3)=2, n(Na2O)/n(SiO2)=0.7, n(H2O)/n(Na2O)=43, under the reaction temperature at 90-100 ℃ for 6h.关键词
