Cadmium tungstate (CdWO 4) has the wolframite structure, which may be described as being made up of hexagonaly close-packed oxygens with certain octahedral sites filled by Cd and W cations in an ordered way [2]. The crystal structure of tungsten trioxide is temperature dependent. It is tetragonal at temperatures above 740 °C, orthorhombic from 330 to 740 °C, monoclinic from 17 to 330 °C, triclinic from -50 to 17 °C, and monoclinic again at temperatures below -50 °C. The most common structure of WO3 is monoclinic with space group P21/n. The pure compound is an electric insulator, but oxygen-deficient varieties, such as WO2.90 = W…
