Gas Sensitivity of Ferric Oxide Ceramics with Transition-Metal Oxide
Source abstract
Abstract
The ferric oaide system with transition metal oxides such as CuO-Fe2O3 and ZnO-Fe2O3, were Sintered at different temperatures and formed a porous ceramic with a-Fe2O3 and spinel crystal phases. This ceramic possesses a remarked sensitivity to reductive gases. The special property is considered to relate to the ferric vacancy coccentration in a spinel phase. The ferric vacancy concentration varies with composition and heating temperature. The gas sensitivity can be improved by the increment of the ferric vacancy concentration.
