Tungsten bronze, such as cesium tungsten bronze, is often used to make a transparent heat insulation dispersion. And the prepared dispersion has the characteristics of high conductivity, high near-infrared shielding effect, high transparency, electrochromic property, photochromic property, light-to-heat conversion ability, photocatalytic property and dispersion stability.

A Preparation Method of Tungsten Bronze Heat Insulation Dispersion
The precursor is obtained by reacting a reducing agent with tungstic acid and an alkali metal salt solution in a super-gravity rotating bed, and the precursor is hydrothermally treated, and then the hydrothermal product is processed to obtain tungsten bronze nano dispersion. The raw materials are easy to obtain. The price is low, the method is simple, and the production cost is low. Also, it is environmentally friendly and suitable for industrial production. Besides, by utilizing the superior mass transferring ability of the super-gravity rotating packed bed, strengthening the transfer and mixing of solvent-antisolvent, so that the preparation process of the tungsten bronze precursor liquid is performed under highly microscopic and uniform conditions, so that the particle nucleation is uniform.
