Low temperature synthesis of nano-crystalline gadolinium titanate by molten salt route

Abstract

Nano-crystalline Gadolinium Titanate (Gd 2 Ti 2 O 7 ) powder was successfully synthesized by “ Single Step Molten Salt Technique ”. LiCl–KCl eutectic mixture was used as a molten medium for the reaction. The duration of the synthesis was 10 h. Stoichiometric proportion of the reactants were mixed in an (LiCl–KCl) eutectic medium and treated at 750 °C in an electrical resistance furnace. Single phase Gadolinium Titanate compound was obtained by the thermal process. The synthesized powders were characterized using XRD, FT-IR, UV, EDAX and XPS analyses. The morphology of the powder was examined using SEM and TEM techniques. From the above studies, it has been concluded that pure crystalline Gadolinium Titanate powders can be synthesized via low temperature molten salt process.
