Pyrochlore Phase Tungsten Oxide

Pyrochlore phase tungsten oxide multidimensional channels chemical compound and the formula is M2B2O6O '. It is a special form of tungsten oxide, because it has a molecular sieve mesh structure and dielectric stability, so its chemical and physical characteristics have significant change. Not only conductive properties, adsorption performance enhancements, and in catalysis, sensing, electrochromic and fuel and electromagnetic fields have been widely used. The method of production tungsten oxide pyrochlore phase has: soft chemical synthesis and hydrothermal synthesis. Soft chemical synthesis produce pyrochlore phase tungsten oxide is under mild conditions synthesis by inorganic functional materials. It is in low or solution to make reactant in molecular size can be uniform mixing, and the reaction can be controlled step by step. After producing precursor or intermediate the material which having a composition, structure and morphology has finally produce. The hydrothermal synthesis method is under high temperature conditions, water or other solutions in critical or supercritical state, the reactivity increased physical properties and chemical reactivity in solution occur great changes, is a reflection of different from the norm.
