摘要：

NaX molecular sieve films on ceramic paper prepared by in-situ hydrothermal method were investigated. The NaX zeolite seed crystals of a uniform size of 5 mum were synthesized by hydrothermal method in a mother solution having a composition of 3.5Na(2)O: Al2O3 : 2.1SiO(2) : 500 similar to 1000 H2O. These dip-coated NaX seed crystals on ceramic paper lead to further the thickness (20 similar to 100 mum) of NaX film on the substrate at 90degreesC for longer 3similar to7 days in autoclave. Pure zeolite films consisting of a continuous intergrown of 5similar to 20 mum NaX crystal have been prepared on the substrates. The zeolite films were characterized by XRD, SEM, BET and XRF.
