Abstract

The Fe2O3 nanopowders were prepared by Solid Phase Reaction. The phase composition, microstructure, magnetic properties and gas sensor properties were investigated by XRD, TEM, VSM and gas sensor measuring system. It was shown that the precursor could be transformed into -Fe2O3 of the spinel structure when it was sintered at 300 and transformed into -Fe2O3 of the corundum structure when it was sintered at 400 . The gas sensor of -Fe2O3 was more sensitive to the alcohol. In addition, it was found that heat insulation effect was improved evidently by adding two types of nanopowders to the paint.
