WO3 may be applied to prepare ceramic microsphere, which is a kind of nano infrared heat insulation masterbatch. Such new masterbatch may be added in the processing of heat insulation film, and the obtained film has versatility. For example, such film is attached to the glass door and glass window of the building to effectively block ultraviolet rays and infrared rays. The experiment proves that the heat insulation film of nano WO3 can also reduce electricity costs by 30%, and achieve the purpose of energy conservation and emission reduction and high dingality.
In addition, the ceramic microspheres may also be applied to the textile field due to its strong absorption in the mid-infrared (infrared radiation of the human body is 8000-10000nm), thereby achieving the effect of high heat insulation.

This is because the nano heat insulation masterbatch absorbs the infrared and shields sunlight through the nano-tunneling effect when the high-temperature sunlight shines. When a certain saturation value is reached, the nanoparticles start to vibrate and the emission principle appears. When the temperature is low and the sunlight is weak, the heat is released. There is a process of storage and release to achieve the thermal insulation effect of the product. So, the masterbatch may be widely used in textiles, thermal insulation films and plastic sheets.
