Abstract

ZnO and SiC powders were fabricated to make crack-free composite membranes. Parts of some membranes were re-treated with an encapsulation process. These membranes were characterized by XRD, BET, and FE-SEM analyzes. The hydrogen permeation fluxes of the encapsulated and heat-treated membranes after encapsulation were observed using Sievert's type equipment. Values were measured at 1 bar with increasing temperatures. The obtained values of encapsulated and further heat-treated membrane at 298 K were $4.20{\times}10^{-6}$ and $8.64{\times}10^{-5}mol/m^2sPa$, respectively.
