Quartz glass used in modern cutting-edge space technology
Quartz glass, also known as fused silica, is a remarkable material with an exceptionally low coefficient of thermal expansion, making it highly resistant to temperature changes. It exhibits outstanding chemical stability, excellent electrical insulation properties, and consistent ultrasonic delay performance. Additionally, it offers superior transmission in the ultraviolet (UV) range, as well as good visibility in the visible light spectrum and near-infrared wavelengths. Compared to regular glass, quartz glass possesses higher mechanical strength, which makes it ideal for demanding applications.
Due to its unique properties, quartz glass plays a crucial role in various advanced industries, including aerospace, nuclear energy, defense technology, automation systems, semiconductors, metallurgy, chemical processing, lighting, telecommunications, consumer goods, and construction materials. Its versatility and reliability make it an essential component in cutting-edge technological developments.
Quartz glass is manufactured from either natural crystalline quartz (such as quartz crystal or pure silica) or synthetic silica through high-temperature melting processes. The resulting material has excellent workability, allowing it to be shaped into tubes, rods, and other forms similar to conventional glass. Advanced machining techniques using diamond or silicon carbide tools enable the production of intricate instruments and specialized components.
The quality and performance of quartz glass are primarily determined by its purity. Even the smallest traces of impurities can significantly affect its characteristics. Moreover, any minor oversight in the manufacturing process or thermal control can lead to surface defects, reducing product quality and increasing waste. Therefore, strict quality control is essential throughout the entire production cycle to ensure the final product meets the required standards.
