Quartz glass is widely used in the following fields due to its high temperature resistance, high purity, chemical stability, and excellent optical properties:
semiconductor industry
As the core material of chip manufacturing, it is used for diffusion furnace tubes, wafer cleaning equipment, etc., accounting for 45% of the market share. For example, the carrier devices and cavity consumables required for etching, diffusion, oxidation and other processes.
Optical field
Used for photolithography machine mask substrates (transmittance>95%), space telescope lenses, and laser weapon components. Like the laser reflector used in the Apollo moon landing experiment in the United States.
aerospace
Used for spacecraft wind tunnels, observation windows, satellite solar panels, and fighter jet antenna covers, resistant to extreme environments. The window material of China's Shenzhou spacecraft is made of quartz glass.
