Synthesis of ZrO₂–Y₆WO₁₂ solid solution powders by a polymerized complex method

A series of solid solutions (1 − x) ZrO₂ · xY_0.857 W_0.143 O_1.714 (1/7Y₆WO₁₂) of metastable cubic phase were synthesized at 800 °C through a polymerized complex method. Lattice parameter a₀ of solid solutions varies linearly with Y_0.857 W_0.143 O_1.714 content (x). Crystallization began to occur above 400 °C from amorphous precursor to yield at 800 °C fine powders of 6–10 nm and 19–40 m²/g for crystallite size and surface area, respectively.
