Optical quartz glass is also named silicon wafer. It can be used as substrates for semiconductor integrated circuits, optical communications, MEMS, optoelectronic devices, LED and so on. Its main materials are: synthetic fused quartz (JGS1), fused quartz (JGS2), flame fused quartz (JGS3), single crystal quartz crystal. For different types, different performance, different prices, to meet the various uses and requirements of customers, to provide customers with a variety of choices, to provide the most affordable products.
JGS1 is transparent in the ultraviolet and visible spectrum. There is no absorption band in the band range of 185-2500nm; There are strong absorption bands in the band range of 2600-2800nm. Non luminous, light radiation is stable.
JGS2 is transparent in the ultraviolet and visible spectral range; There is no absorption band in the band range of 200-2500nm; There are strong absorption bands in the band range of 2600-2800nm. Non luminous, light radiation is stable.
JGS3 is transparent in visible and infrared spectra and has no obvious absorption band in the band of 2600-2800nm.
Quartz glass is a special industrial glass, made of silicon dioxide, is a good basic material. Quartz glass has a series of excellent physical and chemical properties, such as:
1, high temperature resistance. The softening temperature of quartz glass is about 1730℃, 1100℃ can be used for a long time, and the high temperature can reach 1450℃ in a short time.
2, corrosion resistance. With the exception of hydrofluoric acid, quartz glass has little chemical reaction with other acids. Its acid resistance is 30 times that of ceramic, 150 times that of stainless steel, especially its chemical stability at high temperatures, which is unmatched by other engineering materials.
3, good thermal stability. Glass has a small coefficient of thermal expansion and can withstand drastic temperature changes. Quartz glass heated to 1100℃ or so, in normal temperature water will not burst.
4, good light transmission. Quartz glass has good light transmittance in the whole spectrum from ULTRAVIOLET to infrared. The transmittance of visible light is more than 93%, especially in the ultraviolet band, the transmittance is more than 80%.
5, quartz glass has good electrical insulation. Quartz glass has 10,000 times more resistance than ordinary glass. It is an excellent electrical insulating material with good electrical properties even at room temperature.
