Cesium tungsten oxide particles, also known as cesium tungsten bronze particles, may be used to prepare a transparent blue-black liquid --- nano-ceramic dispersion solution. Experts said that the obtained dispersion solution has high visible light transmission and high infrared shielding effect. When the visible light transmittance is 70%, the infrared blocking rate at 950nm can reach over 90%, and at 1400nm, it can reach 95% or more. Therefore, it can play a role of high heat insulation in the architectural glass.

Experts also said that the effective solid particle content of the cesium tungsten bronze dispersion solution is 20% (adjustable); the dispersed particle size is less than or equal to 40nm (D50); the pH range is 6-7.5 (adjustable); can be dispersed in a variety of acrylic acid, polyester, silicone and other resin systems; clear and transparent of low fog value; evenly dispersed in the resin, its haze after coating drying is less than 1; low agglomeration of nanoparticles after long-term storage ( 6 months).
