Abstract

Dual-phase composite inorganic materials are used as membrane separator for oxygen production, solid oxide fuel cells for power generation, and membrane reactors for catalytic conversion of light hydrocarbons. A new structure of dense dual-phase membrane and its preparation method was presented. The new dual-phase membrane consisted of an oxygen ionic conducting (OIC) ceramic phase defined by compact packing of OIC ceramic particles and a three dimensional film of an electronic conducting (EC) phase covering the surface (or grain boundary) of the OIC ceramic particles. The sintered grains of the OIC-phase develop to a dense bulk particle and the liquid EC-phase formed a continuous three-dimensional film running through the grain-boundaries of the connected OIC phase. The concept was verified using Ba 0.5Sr 0.5Fe 0.2Co 0.8O 3-δ (BSCF) and La 0.15Sr 0.5Fe 0.2Co 0.8O 3-δ (LSGF). The majority phase was the chemically more stable LSGF and the second phase was made of a mechanically and chemically compatible BSCF, rather than a metal, the dual phase composite membrane exhibited a higher oxygen permeability and offered better chemical/mechanical stability than the highly oxygen permeable BSCF membrane.
