The specific applications of quartz weights in the fields of semiconductors and optics are as follows:

Semiconductor field

Manufacturing quartz crucibles: Quartz weights are important raw materials for producing quartz crucibles. In the production process of monocrystalline silicon, quartz crucibles play a crucial role as containers for holding polycrystalline silicon raw materials or monocrystalline recycled materials during the pulling process. The crucible made from processed quartz weights needs to withstand high temperatures and chemical corrosion to ensure the growth quality of single crystal silicon.

Production of quartz furnace core tube: In the manufacturing process of semiconductor chips, diffusion, oxidation, annealing and other processes need to be carried out in a high-temperature and high-purity environment. The quartz furnace core tube made of quartz slag has the characteristics of high temperature resistance, corrosion resistance, and high purity, which can meet the requirements of these processes and provide a stable reaction environment for chip manufacturing.

Making quartz boats: used to carry silicon wafers for transportation and processing in semiconductor production equipment, such as in chemical vapor deposition, photolithography, etching and other processes. Quartz boats can withstand high temperatures and chemical erosion, ensuring the safe transportation and processing of silicon wafers without causing pollution to them.

Optical field

Manufacturing optical lenses and prisms: Quartz weights can be processed into various shapes and specifications of optical lenses and prisms through cutting, grinding, polishing, and other processing techniques. These optical components play important roles in optical instruments such as focusing, imaging, and splitting, and are widely used in fields such as microscopes, telescopes, camera lenses, and laser equipment.

Production of Quartz Window Plates: In optical instruments, quartz window plates are used to protect internal optical components and optical path systems while allowing light to pass through. Window plates made of quartz weights have the characteristics of high transparency, low absorption, high hardness, and wear resistance, which can maintain good optical performance under harsh environmental conditions. They are widely used in equipment such as space telescopes, satellite optical payloads, and high-temperature furnace observation windows.

Making fiber optic preforms: Fiber optic is a core component of modern communication and optical sensing technology, and quartz wool is one of the important materials for manufacturing fiber optic preforms. By doping and drawing quartz weights, optical fiber preforms with specific refractive index distribution and optical properties can be made, and high-quality optical fibers can be drawn for use in optical communication, fiber sensing, laser transmission and other fields.

Manufacturing optical polarizers and filters: Quartz weights can be processed and coated using special techniques to produce optical polarizers and filters. Polarizers are used to control the polarization direction of light and have important applications in fields such as liquid crystal displays, optical communication, and laser technology; Filters are used to selectively transmit or block light of specific wavelengths, playing an important role in fields such as spectral analysis, optical imaging, and optical communication.
