一文了解熔融石英

Core Viewpoint - The article discusses the development, production challenges, and applications of fused quartz, highlighting its growing importance in various high-tech industries and the need for improved production techniques to enhance quality and reduce costs [1][2][3]. Group 1: Classification of Fused Quartz - Fused quartz is classified into two main types: transparent quartz glass with SiO2 content greater than 99.95% and opaque quartz glass with SiO2 content greater than 99.80% [1]. - The industry has seen the development of new varieties, such as optical-grade fused quartz glass and high-purity fused quartz products, by companies like HERAEUS and GEQUARTZ [1]. Group 2: Production Status of Fused Quartz - Jiangsu Province's Donghai County is a key production base for high-purity quartz materials, with local companies using a production process that involves melting selected high-quality quartz raw materials [1]. - Major challenges in production include high melting temperatures, viscosity, and the need for high purity, with impurities needing to be less than 0.0001% [2]. - The current production methods often lead to high energy consumption, accounting for over 50% of production costs, which impacts profitability [2]. Group 3: Applications and Market Overview - Fused quartz is widely used in various fields, including electronics, military, aerospace, optical communications, and chemical engineering due to its excellent physical and chemical properties [3]. - In the electrical light source industry, fused quartz products are used in various lighting applications, including energy-saving lamps and sterilization lamps [4]. - The fiber optics industry relies heavily on high-purity fused quartz materials for the production of optical fibers, with strict requirements for size and purity [5]. - In aerospace, fused quartz is utilized for its low thermal expansion coefficient and excellent radiation resistance, making it suitable for applications in telescopes and spacecraft [5]. - The semiconductor industry has seen rapid growth in the use of fused quartz for various processes, including doping and diffusion of silicon wafers [5]. - Fused quartz is also essential in radar technology, chemical production, metallurgy, and precision instruments due to its stability and high-temperature resistance [5].
