Vacuum seeding and secondary growth route to sodalite membrane
چکیده انگلیسی

Sodalite membrane has been successfully fabricated on tubular porous α-Al2O3 supports by secondary growth method with vacuum seeding. In the seeding process, the colloidal seeding particles were agglutinated not only onto the surface of alumina support but also within the pores by vacuum sucking method. To obtain defect-free sodalite membrane, the sodalite crystals were grown directly on the alumina support in a mixture solution containing alumina and silica species under the hydrothermal reaction condition. The as-synthesized sodalite membranes were characterized by X-ray diffraction (XRD) analysis and scanning electron microscopy (SEM). The thickness and the quality of sodalite membrane could be controlled by the hydrothermal reaction time (12∼24 h) and temperature (100∼150 °C) under the mother solution of 5Na2O : 2SiO2 : Al2O3 : 1000H2O.
