Low sintering temperature enhancing colossal dielectric permittivity and humidity sensitivity in Ta5+ substituted TiO2 ceramics via high energy ball milling

Abstract Nanostructured 1% and 10% Ta5⁺-substituted TiO2 (TTO) ceramics were synthesized via high-energy ball milling and sintered at 1200 °C and 1300 °C to investigate their dielectric and humidity sensing performance. XRD confirmed a single-phase rutile TiO2 structure in both the powdered and sint...
