According to the China Building and Industrial Glass Association, the global quartz market exceeded 20 billion yuan in 2015, of which semiconductors accounted for 45.53%, photovoltaics accounted for 23.76%, optical communications accounted for 16.20%, optics accounted for 9.50%, and light sources accounted for 5.18%.
High-end quartz is still dominated by overseas supplies, such as Momentive, Heraeus, Tosoh, 3M, Shin-Etsu, Qsil, etc.
According to the calculation of each downstream demand, it is estimated that the global quartz material demand for 2018-2020 will be 25.265 billion. Quartz producers have a monopoly; as downstream industries shift and domestic substitution is accelerating, domestic quartz companies are gradually moving into high-end applications such as semiconductors, optical fibers, aerospace, and electric light sources.
