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…
