A Simple Dissolved Metals Mixing Route to Prepare Nanostructured Mg_(0.8)Zn_(0.2)TiO_3 Solid Solution

摘要

A study of liquid mixing route to synthesize high purity Mg_(0.8)Zn_(0.2)TiO_3 nanopowder, a candidate dielectric ceramics, has been successfully performed. Formation of the phases on the dried powder was studied using TG/DTA, XRD and FT-IR data. Rietveld analysis on the collected XRD patterns confirmed the formation of solid solution in the system. Such solid solution can be obtained from the powder calcined at 500 °C, but calcination at 550 °C gave rise to the most optimum molar purity up to 98.5% without intermediate phases. The role of Zn ions on the formation of solid solution was also discussed. Homogeneity of particle size distribution and nano-crystallinity of the system was verified from the particle size analyzer data, TEM image and the Rietveld analysis output.
