Tungsten trioxide Usage And Synthesis
DescriptionTungsten trioxide is a chemical compound consisting of oxygen and the transition metal tungsten. It occurs naturally but rarely in the form of hydrates in some kinds of minerals. It has various applications. In industry, it can be used for making x-ray screen phosphors, fireproofing fabrics and gas sensors as well as a pigment in ceramics and paints. It can also be used for the preparation of electrochromic windows or smart windows. In addition, it can be used in semiconductors. It, together with titanium dioxide, has the potential to become an efficient photo-catalyst under visible light irradiation. Recent study has shown that mesoporous tungsten trioxide polyaniline nanocomposite can be used as an anode material for high-performance lithium-ion batteries.
