Abstract
Disclosed are potassium cesium tungsten bronze solid solution particles of the formula KCsWO, where x+y≦1 and 2≦z≦3. The particles are for instance micron or nano scaled particles. Also disclosed are organic or inorganic compositions comprising an organic or inorganic substrate and incorporated therein the present potassium cesium tungsten bronze solid solution particles. The substrates are for instance plastics, coatings, inks, adhesives, ceramics or glass. Also disclosed is a method for the preparation of the present potassium cesium tungsten bronze solid solution particles, which method comprises mixing a suitable tungsten source with a salt of potassium and a salt of cesium to form a powder mixture and exposing the powder mixture to a plasma torch under a reducing atmosphere. The present tungsten bronze particles are suitable NIR absorbers and heat shielding additives.
