Abstract Scope |
Recently, the mixed ionic-electronic conducting (MIEC) and mixed ionic-electronic conducting - redox (MIEC-Redox) liquid oxide membranes have been developed [1-3]. Unlike conventional MIEC ceramic membranes, these liquid membranes demonstrate the highest oxygen selectivity and could be used for separation of ultra-high purity oxygen (above 99.999 % purity) which is in demand for semiconductor, chemical, biological, metallurgical, and pharmaceutical industries. However, before this is implemented, important issue has to be addressed. This issue includes the liquid oxide membrane performance optimization. In this article, the transport properties of liquid oxide membranes as well as the approaches to enhance the performance of these membranes are discussed.
