چکیده انگلیسی
A silicalite/mordenite bilayered self-supporting membrane with disc-shape was synthesized from a layered silicate, kanemite by two steps using solid-state transformation. The mechanical strength (compression strength) of the membrane was greater than 10 kg/cm2. Both sides of the membrane were much different in the morphology and SiO2/Al2O3 ratio. One side (silicalite side) consisted of the intergrowth of prism-like crystals (ca. 1–2 μm), while the other side (mordenite side) was composed of scale-like crystals (ca. > 1 μm). The SiO2/Al2O3 ratios for the respective sides were less than 600 and 15. The XRD patterns were consistent with those of the silicalite and mordenite structures.
