Abstract
The processes for deposition of selective vanadium-containing layers on the external surface of α-Al2O3 based tubular ceramic membranes, for use in the petrochemical industry, were investigated. The V2O5 · 1.6H2O layer deposited on the outer surface of the ceramic membrane was obtained by the sol-gel method. The temperature of thermal treatment was varied from 400 to 700°C. The chemical stability of membranes in an aqueous environment with the applied layer subjected to thermal treatment at 650°C was investigated. The chemical stability of the membranes with the V2O5 layer applied was found to be within the pH range of 5 to 8. The optimum temperature for thermal treatment to obtain a layer with high adhesion to the substrate was determined to be 650°C.
