Enhanced humidity sensing properties of Ta₂O₅ and ITO doped rutile-TiO₂ porous ceramics.

ABSTRACT: In this study, we investigated the humidity sensing properties of TiO₂-based ceramics doped with tantalum pentoxide (Ta₂O₅) and indium tin oxide (ITO). Pure TiO₂, 1%Ta-doped TiO₂ (1%TTO), 1%ITO-doped TiO₂ (1%ISTO), and 1%(Ta₂O₅ + ITO) co-doped TiO₂ (1%ISTTO) ceramic samples were obtained by sintering at 1200 °C for 3 h. The rutile phase was observed in all samples. The lattice parameters of the single and co-doped samples were larger than those of pure TiO₂, confirming the substitution of dopants. Porosity was observed in all ceramics. The mean grain sizes of all doped samples were significantly reduced compared to undoped TiO₂. A homogeneous element dispersion was obser
