The preparation of CoWO₄/WO₃ nanocomposite powder

Abstract

Ammonium metatungstate and cobalt nitrate were mixed at the molecular level in distilled water and then spray-decomposed to CoWO₄/WO₃ nanocomposite powder. The particle morphology, crystalline size, forming course, chemical composition and phase structure of the powder were studied by SEM, TEM, DTA-TG, IR and XRD, respectively. Results show that the powder is homogeneous, spherical and nano-aggregated.
