The Effect of Aging on Synthesis of Zeolite at High Temperature
Zeolite are used as adsorbent, catalyst and ionexchang material. But it limited to extend the usage of the zeolite since almost zeolite synthesized by hydrothermal method. The purpose of this study was to synthesis zeolite by calcination at high temperature due to extend the application of zeolite, as ceramics process. The effect of aging temperature and time, crystallization temperature on the synthesis of zeolite has been studied. Aging was performed at room temperature～70℃ during 0～3days. After aging, zeolite precursor sinter for 1 hours at 300, 400,500℃ in furnace. The resulting materials were characterized by XRD, TG, SEMWhen the aging time is less than I day zeolite was not synthesized. But zeolite A obtained from precursor of aging time is more than I day at all firing temperature. As a result the aging time and aging temperature is increased, the zeolite synthesis time is decreased. Therefore aging is benefit process on synthesis of zeolite at high temperature.
