Cs0.33WO3 nanoparticles are cesium tungsten bronze nano powders. Also, they are new environmentally friendly dingal particles, which may be used to prepare a transparent thermal insulation paper. The prepared thin "paper" is transparent heat-insulating film, which may be used in the field of architectural glass. So, what chemical methods can be used to prepare nanopowder?

Experts said that one of the chemical preparation methods of the nano powder is a chemical precipitation method, which mainly includes a coprecipitation method, a uniform precipitation method, and the like. What is the coprecipitation method? The so-called coprecipitation method refers to a method of adding a precipitant to a solution containing a plurality of cations to completely precipitate the metal ions. What is the uniform precipitation method? The uniform precipitation method refers to a method in which a substance which can slowly form a precipitating agent is added to a solution to uniformly precipitate a precipitate in the solution. Such precipitation method overcomes the local non-uniformity of the hydrothermal synthesis reactor precipitant caused by the direct addition of the precipitant to the solution from the outside.
