    Abstract

    Cubic Y6WO12, which has a defect fluorite-type structure with disordered cation and anion sublattices, was synthesized for the first time at the low temperature of 600°C by a polymerized complex method. The crystallization process of Y6WO12 from an amorphous precursor has been investigated in detail using TG-DTA, XRD, and TEM. Above 400°C, the cubic phase began to crystallize upon decomposition of the organic materials in the precursor. The crystallite size of the cubic Y6WO12 increased from about 5 nm at 600°C up to about 35-40 nm at 1000°C. Above 1200°C, the cubic phase transformed to rhombohedral Y6WO12, which is a stable phase.
