Cs0.33WO3 particles may be used to prepare an environmentally friendly ceramic microsphere with both properties of UV shielding masterbatch and infrared shielding masterbatch. The ceramic particles are prepared using inorganic nano grain size cesium tungsten oxide (nano cesium tungsten bronze) as raw material by processes of unique grinding dispersion, wet granulation and organic-inorganic ding.

The new type of heat insulating masterbatch of cesium tungsten bronze nanoparticles has been widely used in the transparent coloring of transparent plates, bottles, films and various films. Also, such masterbatch may also be used in the places where high color fastness and heat insulation performance are required. By adding cesium tungsten bronze ceramic particles to the plastic substrate, it is possible to absorb more than 99% of ultraviolet light between 280-380nm, while maintaining excellent transparency of the product and minimizing the influence on the original color of the product. In addition, since cesium tungsten bronze is an inorganic substance, the service life of its products can be greatly extended. At the same time, cesium tungsten bronze is also suitable to be added in the process of plastic products requiring for long-term outdoor use.
