Abstract
Nanosized aluminum tungstate Al2(WO4)3 was prepared by co-precipitation reaction between Na2WO4 and Al(NO3)3 aqueous solutions. The powder size and shape, as well as size distribution are estimated after different conditions of powder preparation. The purity of the final product was investigated by XRD and DTA analyses, using the single crystal powder as reference. Between the specimen and the reference no difference was detected. The crystal structure of Al2(WO4)3 nanosized powder was confirmed by TEM (SAED, HRTEM). In additional, TEM locality allows to detect some W5O14 impurities, which are not visible by conventional X-ray powder diffraction and thermal analyses.
