Numerous studies have been conducted in recent years on the partial oxidation of methane to synthesis gas (syngas: CO 1 H ) with air as the oxidant. In partial oxidation, a mixed-oxide ceramic membrane selectively transports oxygen from 2 the air; this transport is driven by the oxygen potential gra
It is well known that homogeneous mixed oxides (A,B)O show kinetic demixing of the cations when exposed at high temperatures to an oxygen potential gradient. This paper shows that when the cation distribution can be described by a random mixing model (the random alloy model) the resulting demixing a
