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…
