Effect of solvents on the microstructure of CaWO<inf>4</inf> prepared by a solvothermal synthesis
Different sizes of nanostructured CaWO 4 have been prepared by a simple solvothermal synthesis at a low temperature of 160 °C for 6 h through the reaction between Ca(NO 3 ) 2 ·4H 2 O and Na 2 WO 4 ·2H 2 O using various solvents as the reaction medium. The products, characterized by X-ray diffractio...

| Summary: | Different sizes of nanostructured CaWO 4 have been prepared by a simple solvothermal synthesis at a low temperature of 160 °C for 6 h through the reaction between Ca(NO 3 ) 2 ·4H 2 O and Na 2 WO 4 ·2H 2 O using various solvents as the reaction medium. The products, characterized by X-ray diffraction (XRD), were specified as pure CaWO 4 with the scheelite structure. Scanning electron microscope (SEM) and transmission electron microscope (TEM) analysis showed that the particle sizes are mainly related to the physical and chemical properties of the solvents used in the solvothermal synthesis. Photoluminescence properties were also investigated. |
