Tungsten Oxide

Monoalkyl phosphate is an important surfactant, widely used in chemical fiber, textile, leather, plastics, paper making and cosmetics.  Monoalkyl phosphate usually synthesized by the esterification of phosphoric acid with aliphatic alcohols by esterification. The commonly used phosphorus agents are three oxychloride (POCl 3 ) and phosphoric acid. When phosphorus oxychloride is used as an agent for HCL, it is easy to cause environmental pollution, when phosphoric acid is used as a phosphate agent, although it is environmentally friendly, it is difficult to synthesize monoester, diester and three ester because of the low activity of phosphoric acid. Is there a way to improve the activity of phosphoric acid to help balance the benefits of the environment? Cesium phosphotungstate is a kind of heteropoly acid. It is a new type of multifunctional catalyst. It has not only oxidation reduction property, but also high catalytic activity and good stability, it can be used for ho

Photocatalysis is a photochemical reaction in the presence of a catalyst, it is a new science and technology. Common photocatalysts include metal oxides (TiO 2 , ZnO, Fe 2 O 3 , Bi 2 O 3 , WO 3 ) and metal sulfides (CdS, MoS 2 , MoSe 2 ). Titanium dioxide TiO 2  is the most white thing in the world, 1 grams of titanium dioxide can paint more than 450 square centimeter area to white. So it's the best paint for making white oil paint. The most well-known is that semiconductor photocatalysis performance of TiO 2 . TiO 2  photocatalysis is widely used because of its high activity, photochemical stability, non-toxic and cheap. Tungsten trioxide TiO 2  is a kind of tungsten compounds that are widely used, It can be used not only for hard alloys, but also for dyes, the most commendable thing is that tungsten trioxide also with excellent photocatalytic performance. Like TiO 2 , WO 3  also has high activity, photochemical stability, non-toxic and so on. If you compare the two, w

Cesium tungsten bronze (Cs x WO 3 ) is synthesized by solid phase method or liquid phase method with cesium carbonate and sodium tungstate as raw materials. Cesium tungsten bronze is also called cesium tungstate.  Cs x WO 3  is a non stoichiometric functional compound with a special structure of oxygen eight surface, with low resistivity and low temperature superconducting properties. But in recent years, cesium tungsten bronze is popular for its excellent UV and near infrared shielding performance, with high efficiency, insulation and light reflection effect, this makes it good in the manufacture of special glass, high-end insulation film and LCD screen manufacturing. In recent years, with the increasing popularity of cesium tungsten bronze, more and more scholars have begun to discuss the liquid phase preparation of cesium tungsten bronze. Some scholars have adopted the hydrothermal method to obtain cesium tungsten bronze, sodium tungstate and cesium carbonate were used as r

Sodium tungstate , Na 2 WO4•2H 2 O, a tungstate of sodium, is useful as a source of tungsten. It is prepared from tungsten ores to manufacture tungsten by reducing it. It is often found as dihydrate.
