摘要：

A　transparent　seed　(guiding　agent)　solution　was　prepared　by　using　sodium　aluminate　as　the　aluminium　source　and　silica　sol(Ludox)　as　the　silicon　source.　The　aging　time　of　the　seed　solution　was　around　6　hours　for　best　crystallization　of　Nay　zeolite　under　the　conditions:　the　molar　composition　of　the　reactant　mixture　was　n(Na2O):n(Al2O3):　n(SiO2):n(H2O)=8:1:15:220,　at　crystallization　temperature　of　100°C　for　4　hours.　Identified　by　XRD,　SEM,　TEM,　and　BET　techniques.　Results　indicated　that　the　synthesized　product　was　NaY　whose　particles　were　in　relatively　uniform　size　of　about　150-200　nm　in　nano-size　scale.
