Abstract
Ceramics have been extensively used for gaseous molecular separation. In our present research, the procedure to fabricate membrane filters along with SEM studies for multi-layered structures are explained and the importance of high temperature and pressure are discussed in detail. The base material of the multi-layered filters base ceramic material was produced at high pressure of 1400oC, within a period of an hour. Meanwhile, the over layer was generated on the base material by Ni evaporation, using electron beam technique as well. Our studies indicated that the granular ceramics, as a base material, which was formed by sintering contains porosities and cavities due to the applied pressure. The SEM studies show, that the size of porosities ranges from tens to hundreds of microns. Our results are also discussed in terms of the importance of pressure and temperature in fabrication of these membranes.
