Helium‐Permselective Amorphous SiC Membrane Modified by Chemical Vapor Infiltration
Source abstract
Abstract
Helium‐permselective silicon carbide (SiC) membrane was successfully synthesized on an outer surface of γ‐alumina‐coated α‐alumina porous support by both pyrolysis of polycarbosilane without oxygen‐curing process and chemical vapor infiltration (CVI). An amorphous SiC membrane possessed He permeance of 7.7×10−8 mol · m−2 · s−1 · Pa−1, He/CO2 permselectivity of 64, and He/H2 permselectivity of 4.4 at 873 K. CVI process is an effective way to increase permselectivity of gases with small kinetic diameter.
