Fabrication and Characterization of Multilayer α-Alumina NF Membranes abstract

Multilayer ceramic membranes were successfully fabricated via a controlled method. Tubular alumina porous support systems with an open porosity about 48% dip-coating and pore size in the range of 100–600 nm were used as membranes substrate. Submicron and nano alumina powders were used to prepare membranes intermediate and top layers, respectively. The effects of the several parameters on the structural properties of the prepared membranes were studied to get an appropriate pore size and defect-free surface. The morphology and multilayer structure of the final NF membranes were characterized using SEM and optical microscopy (OM). The pore size distribution of multilayer NF membranes was measured by mercury porosimetry (MP).
