Nano grain size yellow tungsten oxide may be applied to produce nano-ceramic dispersion solution, thereby playing a role of grinding. The pulverization of raw materials is an important process in the preparation of ceramic, especially the pulverization of material of micron particle size consumes more time and energy. In the wet ball milling process, the powder tends to be agglomerated due to the collision, closeness, and attraction between molecules or particles, resulting in “reverse grinding” phenomenon. In other words, in the pulverization process, the particle size of material will be getting larger if the grinding continues after the material reaches certain fineness.
While by adding the ceramic dispersion solution, the dispersion solution can be firmly adsorbed on the cracks of the particles and can penetrate deep into the cracks. The new interface formed during the particle crushing process, and it will be quickly wrapped by the dispersion solution, which hinders the recombination of the new interface, thereby accelerating the crushing process, significantly shortening the pulverizing time, saving energy consumption and improving grinding efficiency.
