Cesium Tungstate Nanopowder Applied for Near-infrared Shielding Material

Cesium tungstate nanopowder may be applied for preparing near-infrared shielding material, such as, transparent thermal insulation coating and composite transparent thermal insulation coating with excellent infrared shielding effect. As you may have known, at present, China, Japan, Germany, the United States and many other countries are vigorously developing transparent coating of cesium tungstate or composite coating of cesium tungstate.

According to experts, generally, the dispersion performance of the nanometer cesium tungstate powder is good if the powder has a specific surface area greater than 50 and a primary particle size of less than 25nm. This is because the dispersion of the micron-size powder will be very difficult, and usually, the production process of this grade product is a high-temperature solid phase reaction. And the obtained particles are large, the uniformity is poor. Also, it is difficult to achieve a transmittance of 70% or more, the film has a haze of more than 3%, the coating quality is poor, and the dispersion efficiency is low. So, nano cesium tungstate is popular.
