Polycrystalline powders of CoTeMoO6 were prepared via solid reaction method in this paper.The phase composition and microstructure morphology of samples of CoTeMoO6 under different temperature systems were studied,as well as IR and UV-Vis spectra.The results show that when the sintering temperature rises to 540-560℃,single phase of CoTeMoO6 with good crystallinity and high purity can be got.The powders of pure phase being sintering at 600℃,preferential growth of microcrystalline along the crystal plane of(0...
