Cesium tungstate, or cesium tungsten oxide (CTO), is mainly applied for preparing transparent thermal insulating coating as it has a strong absorption in the near-infrared (NIR) region. Also, cesium tungsten oxide (Cs0.33WO3) nano powder exhibits an excellent photothermal conversion property in the NIR region, owing to the free electrons or polarons. And the NIR absorption and photothermal conversion property became more significant with decreasing particle size or increasing particle concentration.

Cesium tungstate for preparing heat insulating glass coating is Cs0.33WO3 nano powder with high purity of 99.9%. Wherein, the Cs0.33WO3 particles are ground into nano particles. After that, Cs0.33WO3 nano powder is prepared into stable aqueous dispersion.

Cesium tungstate is mainly applied for manufacturing transparent heat insulating glass as its nanoparticles (Cs0.33WO3 nanoparticles) have near-infrared (NIR) shielding ability and transparent heat insulating performance. Well, do you know F-doped Cs0.33WO3-xFx particles? A material that has improved near infrared shielding ability than undoped Cs0.33WO3 particles.

Cesium tungstate for preparing window thermal-insulation film is dark blue powder with particle size of 50-70nm and purity of 99.9%. Wherein, cesium tungstate nano powder is industrial grade Cs0.33WO3.
