Abstract

An in situ calcination of an aerosol co-deposited (AcD) NiO-Mn2O3 film for the production of a single-phase cubic NiMn2O4 spinel film was investigated. Characterizations of the AcD film were performed before, during, and after calcination using SEM, XRD and electrical measurements. It could be shown that in situ calcination to mechanically stable films with single-phase cubic spinel structure is possible. Furthermore, changes in the crystal structure and the NTCR parameters B and ρ25 during calcination could be shown. After in situ calcination, the electrical properties are similar to those of conventional bulk ceramics.
