Potassium cesium tungsten bronze has formula of KxCSyWOz, where x+y≤1 and 2≤z≤3. If the particles of KxCSyWOz are nano particles. The particles are useful as near-infrared (OTR) absorbers and/or heat shielding additive (may be prepared by a plasma torch). And the additive may be applied in organic or inorganic substrates, such as plastics, paints, enamels, inks, adhesives, ceramic or glass. The potassium cesium tungsten bronze particles exhibit properties of a solid solution. I.e., they are uniform and present in a…

High-purity cesium tungsten bronze nanopowder may be prepared by solvothermal liquid phase method in a 1500L reactor. Before that, there has been no report on the production of cesium tungsten bronze nanopowder by completely liquid phase method. Many studies have reported that wet chemical liquid phase methods, such as hydrothermal method, solvothermal method and high-temperature pyrolysis method may be used to prepare cesium tungsten bronze nanoparticles. However, they all have the disadvantages of high costs, serious corrosion to equipment, high…

Nano grain size cesium tungsten bronze can absorb infrared light so that it can realize transparent heat insulation. And it has the best absorption on near-infrared rays among antimony-doped tin oxide (ATO), indium tin oxide (ITO), lanthanum hexaboride, and cesium tungsten bronze nanoparticles. How to apply nano grain size cesium tungsten bronze to thermal insulation materials? 1. Add cesium tungsten bronze nanoparticles with the ability of absorbing infrared light into the resin to obtain transparent thermal insulation coating and coat…
