1) The semiconductor quartz market has the highest market share and has high requirements for the purity of quartz. It usually needs to be certified by Tokyo Electronics, American Applied Materials, Lam Research, etc .; many high-end quartz material manufacturers in China have passed multiple certifications.
2) Optical communication quartz is mainly used for optical fiber preforms, mandrels, sleeves and related auxiliary materials, of which core rods and 90% of sleeves are imported; many high-end quartz material manufacturers in China have broken through the sleeve preparation technology, and we expect With the construction of domestic optical fiber and cable, the domestic substitution is rapidly started.
3) Quartz fiber is mainly used in aviation's wave-transmitting reinforcement materials, heat insulation and high temperature resistant materials. In the future, with the increase of national defense budget and the launch of national key engineering projects, we expect the demand to increase rapidly in 18-20 years.
