TiO2–CeO2 Ceramic Nanocomposites: Synthesis, Characterization, and Dielectric Characteristics at Low Titania Concentrations: Synthesis, Characterization, and Dielectric Properties of TiO2-CeO2 Ceramic Nanocomposites at Low Titania Concentrations

Abstract

TiO2(x)–CeO2 (1−x) TiO2 and CeO2 nano-particles produced by the polymeric citrate precursor technique were used for low TiO2 composition of 5, 10, 15 and 20. The characteristics of these nanocompositions were the use of powder x-ray diffraction, electron microscope transmission, electron microscopy scan, x-rays energy dispersion analysis and BET surface area study. The special surface area of the preparations for nanocomposites within the range of 239–288 g−1 was shown in BET tests. For all TiO2 Titanium-Ceria nanocomposites the lowest average particle sizes of 30 nm and the largest surface area of 288 m2 is the nanos generated. Dielectric characteristics are accessed via frequency and temperature. TiO2(x)–CeO2 (1−x) Dielectric constant at room temperature at 500 kHz was x = 0.20.
