چکیده انگلیسی
The deposit thin layers has been realized with a sol prepared with the destabilization of colloïdal solutions process. This is possible by infiltrating a low viscosity sol or by direct coating on to an ultrafiltration. We have chosen to study ZrO2 oxide for their interesting properties and the interest which may bring in the domain of inorganic membranes chemical and mechanical high resistance. The structural characterisation was studied by differential thermal analysis, infrared spectroscopy, X-ray diffraction. The textural characterisation by nitrogen adsorption-desorption allowed us to observe the variation of the surface area, porous volume and pore diameters according to temperature. Scanning electron-spectroscopy observation showed homogeneous layers without cracking. The sol-gel process is particularly well suited at the realization of thin microporous layers. In this paper, some experimental results on the synthesis and characterization of inorganic membrane will be presented.
