Tungsten Oxide

  What is Cesium Tungsten Bronze? Cesium tungsten bronze, also known as cesium tungsten oxide, is an inorganic nanomaterial with good near-infrared absorption effect. 780nm) new functional materials with high transmittance. English name: Cesium Tungsten Bronze Molecular formula: Cs0.33WO3 Molecular weight: 276 CAS number: 189619-69-0 Physical and Chemical Properties of Cesium Tungsten Bronze: The molecular structure of cesium tungsten bronze is oxygen octahedral structure, the purity is higher than 99.9%, the bulk density is 1.5g/ml, the particle size is relatively uniform, the primary particle size is about 30nm, the specific surface area is about 50m2/g, and it is not easy to agglomerate, non-toxic , Non-radioactive features. The Production Method of Cesium Tungsten Bronze: Method 1: Preparation of Cs0.33WO3 from Na2WO4•2H2O and Cs2CO3 1. Using sodium tungstate Na2WO4•2H2O as raw material, prepare a sodium tungstate solution with a concentrat...

  What is Tungsten Disulfide? Tungsten disulfide (WS2, Tungsten Disulfide) is a low-dimensional transition metal sulfide with a layered structure similar to that of graphene. It is widely used in optoelectronics, lubrication, and energy storage due to its good mechanical, thermal, optical and electrical reasons. , medical and other fields. Physical Properties of Tungsten Disulfide: Appearance is black gray powder, density 7.6g/cm3, slightly soluble in cold water, soluble in hot water, insoluble in inorganic acids, alkalis and alcohols except concentrated nitric acid and hydrofluoric acid mixture, but soluble in molten alkali. Because W in WS2 is in an intermediate valence state, it has strong reducing and oxidizing properties, and is easy to react with hot concentrated sulfuric acid, nitric acid, aqua regia and other strong oxidants to produce WO3 or WS3; in addition, heated to 1250 in vacuum ℃ will decompose into tungsten and sulfur. Tungsten Disulfid...
