What are the characteristics of JGS1 quartz glass?

Because glass is translucent and reflective, and easily colored, it is often used in occasions with lighting and color requirements, such as optical instruments and various art decorations. Modern technology has brought new vitality to the glass industry, and has also greatly improved the performance of glass. Below we will briefly introduce the characteristics of JGS1 quartz glass, and explain why quartz can be used as optical glass.

　　What are the characteristics of JGS1 quartz glass?

　　1. High temperature resistance

　　The softening point temperature of JGS1 quartz glass is about 1730, and it can be used for a long time at 1100, and can reach as high as 1450 in a short time.

　　2. Corrosion resistance

　　Except for hydrofluoric acid, JGS1 quartz glass hardly reacts with other acids. Its acid resistance is 30 times that of ceramics and 150 times that of stainless steel. In particular, its chemical stability at high temperatures is unmatched by any other engineering material.

　　3. Good thermal stability

　　JGS1 quartz glass has a very small coefficient of thermal expansion and can withstand drastic temperature changes. If JGS1 quartz glass is heated to around 1100, it will not burst even if it is put into room temperature water.

　　4. Good light transmission performance

　　JGS1 quartz glass has good light transmission performance in the entire spectral band from ultraviolet to infrared. The visible light transmittance is above 95%, especially in the ultraviolet spectral region, the transmittance can reach more than 80%.

　　5. Good electrical insulation performance

　　The electrical resistance of JGS1 quartz glass is 10,000 times that of ordinary glass. It is an excellent electrical insulating material and has good electrical properties even at high temperatures. Due to its excellent physicochemical properties, JGS1 quartz glass is widely used in the fields of electric light sources, semiconductors, optical communication, military industry, metallurgy, building materials, chemicals, machinery, electric power, and environmental protection.

　　The optical characteristics of JGS1 quartz glass are unique. It can not only transmit far-ultraviolet spectra, but also transmit visible light and near-infrared spectra, which is superior to all ultraviolet transmission materials. Users can select the required varieties from the 185-3500 m band according to their needs. Because JGS1 quartz glass has high temperature resistance, a very small coefficient of thermal expansion, good chemical and thermal stability, and bubbles, stripes, uniformity, and birefringence comparable to ordinary optical glass, it is an important optical material for optical systems to have high stability in various harsh environments.

The structure, impurity content, OH gene, NO, CO, etc., are the main factors affecting the spectral transmittance. Poor bonding of oxygen atoms has an absorption peak at 0.24, and JGS1 quartz glass containing OH groups has a significant absorption peak at 2.7 due to molecular vibration. Low ultraviolet transmittance is mainly due to the high content of metal impurities leading to atomic absorption spectra.

The above is some knowledge about JGS1 quartz glass. I hope it can help you understand the relevant information and choose the product that suits your needs.
