Nano yellow tungsten oxide may be used for preparing nano-ceramic dispersion solution so that this type of dispersion solution will have a lot of characteristics such as good dispersion effect, high solid content and low viscosity. And it is easy to use. Also, it does not deteriorate and solidify for long-term storage. More importantly, it minimizes the use of solvents.
There are many optional solvents, including ethanol, isopropyl alcohol, xylene, butyl acetate, toluene, propylene glycol methyl ether, and so on. And therefore, it can well match a variety of coating systems and improve compatibility.
The reason why yellow tungsten oxide can to be used in ceramic dispersion solution is that YTO has photochromic properties. The photochromic phenomenon refers to that when a compound A is irradiated with light of a certain wavelength, a specific chemical reaction can be performed and another product B is obtained, and the absorption spectrum of the compound A changes significantly due to the change of the structure. Under the influence of light of another wavelength or heat, it can new_ to its original form. Photochromism is a reversible chemical change.
