GAS and Pressure Sensing Fe2TiO5 Based Materials

Investigating the Gas and Pressure Sensing Abilities of Fe2TiO5 Based Materials

Abstract

In order to study the applications of the Fe2TiO5 based materials the samples are prepared by standard ceramic technique. The single-phase formation of the pseudobrookite is confirmed by XRD technique. The retention of amount and proportion of LiAl in the ceramics is confirmed by ICP technique. The ac and dc resistivity of the ceramic increases considerably whereas the interfacial contribution to the dielectric constant decreases by intercalation of LiAl. The magnetic hysteresis and susceptibility measurement shows that LiAl enhances the magnetic ordering. The intercalated samples are sensitive to pressure as well as gases (O2 and CO2).
