Core Viewpoint - The article provides a comprehensive overview of quartz glass, including its types, standards, manufacturers, and product specifications, aiming to assist users in selecting appropriate materials for various applications [2][25]. Group 1: Introduction to Quartz Glass - Quartz glass is a special industrial glass made from high-purity silicon dioxide (SiO2), categorized into natural quartz glass and synthetic quartz glass [2]. - The application fields of quartz glass are extensive, with numerous manufacturers and a wide variety of product grades available, leading to challenges in material selection for users [2]. Group 2: Standards for Quartz Glass - Domestic quartz glass follows the construction industry standard JC/T 185, which has undergone three revisions in 1981, 1996, and 2013, categorizing quartz glass based on optical spectrum bands [4][5]. - International standards related to optical glass, such as MIL-G-174B and ISO 12123, provide references for evaluating the quality of quartz glass [5]. Group 3: Manufacturers and Product Grades - Domestic manufacturers include Feilihua, China National Building Material Group, Changfei Quartz, Shenguang Optical, Hengxin Quartz, Zhongtian Nantong Crystal, and Jinzhou Haipu New Materials [10][12][15][16]. - Feilihua offers five categories of optical quartz glass, including low-expansion quartz and low-hydroxyl quartz, suitable for high-end optical applications [10]. - China National Building Material Group has four series of optical quartz glass, with JC-Z series being widely used in the ultraviolet band due to its low metal impurity content [12]. - Changfei Quartz categorizes its products based on characteristics, recommending specific models for industrial laser applications [12]. - Hengxin Quartz has three grades based on preparation methods and hydroxyl content, with specific models corresponding to industry standards [15]. - Jinzhou Haipu New Materials produces two grades of optical quartz glass, corresponding to industry standards JGS1 and JGS3 [16]. Group 4: International Manufacturers and Product Grades - International manufacturers include Corning, Heraeus, Nikon, Ohara, and Tosoh [18]. - Corning's optical quartz glass, known as High Purity Fused Silica (HPFS), includes three main grades, with specific applications in infrared and deep ultraviolet fields [18]. - Heraeus offers a range of optical quartz glass grades, with the Suprasil 300 series being a top choice for low absorption applications in the near-infrared range [20]. - Nikon's optical quartz glass has four grades, with specific applications in ultraviolet and visible light [21]. - Ohara's optical quartz glass includes several series optimized for various optical and semiconductor applications [23]. - Tosoh's optical quartz glass features low hydroxyl content, making it suitable for deep ultraviolet applications [23].
