It is mainly used in the traditional fields such as colored glass, ceramics, alkali - manganese battery and chemical reagent. In recent years, it has been widely used in high-tech fields such as photoelectric industry and military field, especially for the processing of indium tin oxide (ITO) target, the manufacturing of transparent electrodes and transparent thermal reflectors, and the production of flat liquid crystal display and defoamer.
