Cesium tungsten bronze powder, mainly nano grain size cesium tungsten bronze powder, may be used for the preparation of nano-ceramic color master. And thus it may be added to nano-ceramic powder for the production of nano-ceramic material. Adding cesium tungsten bronze nanopowder to the nano-ceramic masterbatch not only can achieve good coloring effect, but also can improve the performance of the ceramic. For example, such color master improves the room temperature mechanical properties of the ceramic matrix material, and improves the high temperature performance as well.
In addition, the particle size of the ceramic powder determines the microstructure and macroscopic properties of the ceramic material. If the particles of the powder are uniformly deposited, the sintering shrinkage is uniform, and the grains are uniformly grown. Then, the smaller the particles, the smaller the defects produced, and the higher the strength of the prepared material. This means that the added nano grain size cesium tungsten bronze also needs to have a uniform particle distribution with small particles.
