Material Properties
• Chemical Properties
Silica glass is a material with excellent chemical stability. It has outstanding resistance to water. And it resists both dilute and concentrated acids comparatively well, even at elevated temperatures (up to about 100 ℃), relative to other current commercial glasses. There are the only exceptions of hydrofluoric acid (which already reactsat room temperature) and phosphoric acid (at temperatures above 200 ℃). Silica glass shows only a limited resistance to alkaline solutions, particularly at elevated temperatures.
• Mechanical Properties
Silica glass is a hard and brittle material with low tensile strength and high compressive strength, with compressive strength being 20 times that of tensile strength.
• Thermal Properties
Silica glass resists to high temperature to above1000℃, and it has very good thermal shock resistance, it is a poor conduct or heat.
• Electrical Properties
Clear silica glass is one of the best electrically insulating substances, suitable particularly for applications at higher temperatures. Its surface electrical conductivity is very low, since it is not hygroscopic and no water film layer containing eluted alkalis is formed on its surface, as happens with conventional silicate glasses. Clear silica glass also has a high electrical disruptive strength and low dielectric losses，even at elevated temperatures.
• Optical Properties
An important difference between silica glass and ordinary glass is its good transmittance throughout the entire spectrum, especially in the ultraviolet and deep ultraviolet spectra, which is not possessed by general optical glass. There are different cutoff wavelengths in the ultraviolet band, and hydroxyl groups produce deep absorption peaks in the infrared band.
• Radiation Resistance
Compared with ordinary glass, silica glass has excellent radiation resistance. Among them, synthetic quartz glass has the best radiation resistance and hardly produces color centers.
