Wholesale Large Diameter Fire Polished Quartz Glass Tube Using for Lab Test

Quartz glass in the ultraviolet to infrared light throughout the spectral band have good light transmission properties, visible light transmission rate of 93% or more, especially in the ultraviolet spectral region, the maximum transmission rate of up to 80% or more. The resistance value of quartz glass is equivalent to 10,000 times that of ordinary glass, which is an excellent electrical insulating material, even at high temperatures, it also has good insulating properties.

The softening point temperature of quartz glass is about 1730°C. It can be used for a long time at 1100°C, and the maximum temperature for a short time can be up to 1450°C. In addition to hydrofluoric acid, quartz glass almost no chemical reaction with other acids, and its acid resistance is 30 times that of ceramics, 150 times that of stainless steel, especially at high temperatures, the chemical stability of any other engineering materials are incomparable. The thermal expansion coefficient of quartz glass is extremely small, can withstand drastic temperature changes, the quartz glass will be heated to about 1100 ℃, into the room temperature water will not blow up.
