How to select the suitable quartz glass grade for projects?The core of selection is to combine the working spectral band and actual working environment. If your project focuses on deep ultraviolet transmission such as UV lithography and ultraviolet detection, JGS1 is the preferred option. For conventional visible light and near-ultraviolet optical equipment, JGS2 can fully meet the requirements. I...

Q6: What purity grades of quartz glass can you supply?A: We provide quartz glass with three different purity levels to match different industry standards and usage requirements. The general industrial grade has a silica content of no less than 99.95%, which meets the demands of conventional high-temperature equipment and ordinary industrial observation windows. The semiconductor grade is the highe...

A: Thermal performance is one of the core advantages of quartz glass. For high-grade synthetic quartz glass, the long-term safe continuous working temperature is 1100°C to 1200°C. In short-time working conditions, it can bear a maximum temperature up to 1300°C. Apart from high temperature resistance, its thermal shock resistance is also outstanding. The qualified products can endure rapid heating ...

A1: They are standard optical quartz grades. JGS1 for deep UV, JGS2 for conventional UV & visible light, JGS3 for infrared applications. ：Optical Quartz Grades JGS1 JGS2 JGS3Detailed Explanation JGS1, JGS2 and JGS3 are internationally recognized standard grades for optical fused quartz glass, classified mainly by spectral transmittance range and hydroxyl (OH) content. Each grade is engineered for ...

Product Classifications & JGS Optical GradesQ4: How many types of quartz glass are there? What are JGS1, JGS2 and JGS3?A: Quartz glass has two mainstream classification methods, divided by manufacturing process and optical grade respectively. Classified by production craft, there are four main categories. Synthetic fused silica features ultra-high purity for high-end optics and semiconductors. Ele...

Q3: What fundamental differences exist between quartz glass and common soda-lime glass?A: Ordinary soda-lime glass is the most common glass for daily use, while quartz glass belongs to high-performance special glass. The gaps between them are reflected in composition, heat resistance, optical performance, chemical stability and production process. In terms of chemical composition, ordinary glass c...

Q2: What is the difference between fused silica and fused quartz?A: These two names are frequently used interchangeably in the industry, but they are distinguished by raw materials, production technology, internal composition and practical performance, and are suitable for completely different application scenarios.AspectFused Silica (Synthetic)Fused Quartz (Natural)Raw MaterialMade from synthetic...

A: Quartz glass, also universally known as fused silica or fused quartz, is a special amorphous inorganic glass material produced by melting high-purity silica raw materials at an ultra-high temperature above 2000 degrees Celsius. Its main chemical composition is silicon dioxide, with the content reaching no less than 99.95%. Different from traditional crystalline quartz, it has no fixed crystal s...
