Quartz Glass Processing  Manufacturers, Traders, Suppliers

Quartz glass is made by melting materials containing silica, such as crystal, silica, and silicon tetrachloride, at high temperatures. Its silicon dioxide content is much higher than ordinary glass, with quartz glass having a silicon dioxide content of 99.999%. Has excellent optical performance, not only has excellent visible light transmittance, but also transmits ultraviolet and infrared rays. Meanwhile, quartz glass is a good acid resistant material. In addition to hydrofluoric acid and thermal phosphoric acid above 300, it can withstand corrosion from sulfuric acid, nitric acid, hydrochloric acid, aqua regia, neutral salts, carbon, and sulfur at high temperatures. Its chemical stability is 30 times that of acid resistant ceramics and 150 times that of nickel chromium alloys and ceramics. It is resistant to high temperatures, heat shock, and has a particularly small coefficient of thermal expansion

Due to its high temperature resistance, extremely low thermal expansion coefficient, good chemical stability, and comparable bubble, stripe, uniformity, and birefringence to general optical glass, quartz glass is an essential optical material with high stability optical coefficient that works in various harsh environments. Quartz glass plates are widely used in industries such as semiconductors, electro-optical sources, semiconductor communication devices, lasers, optical instruments, laboratory instruments, electrical equipment, medical equipment, high-temperature and corrosion-resistant chemical instruments, chemical engineering, electronics, metallurgy, building materials, and national defense. They have a wide range of applications.
We custom produce precision quartz and optical glass products. Our products include: high precision glass and quartz capillary tubes and rods, quartz glass tubes and rods, quartz and optical glass discs / substrates / wafers, CNC machined quartz parts, quartz instruments, various high precision glass parts, ceramic components etc.
In past years, we have successfully developed primary and secondary drawing production processes based on different glass capillaries requirements. Except the round tubes and rods, we can provide non-circular tubes and rods, like square, rectangular, triangle, half round, with single bore, double bores, triple bores or more bores on cross section. Precision is well controlled according to customer's requirement.

Quartz glass plates are usually colorless and transparent. They can transmit far ultraviolet light, which is the best among all UV transparent materials, as well as visible light and near-infrared spectra. According to its optical performance, it can be divided into three categories:
Far ultraviolet JGS1
Transparent in the ultraviolet and visible spectral ranges; There is no absorption band in the wavelength range of 185-2500nm; There is a strong absorption band in the 2600-2800nm wavelength range; Non luminous, stable light radiation.
UV class JGS2
Transparent in the ultraviolet and visible spectral ranges; There is no absorption band in the frequency range of 200-2500nm; There is a strong absorption band in the 2600-2800nm wavelength range; Non luminous, stable light radiation.
Infrared JGS3
Transparent in the visible and infrared spectral range; There is no obvious absorption band in the 2600-2800nm wavelength range.
