The drape is 1.2 mm thick with a working temperature of 1100C. Its low coefficient of thermal expansion also makes it an ideal glass for precision mirror substrates. This Silica Glass Welding Drape is used to cover and protect sensitive areas while welding. Fused quartz possesses a high degree of purity, high chemical resistance, good thermal shock resistance, and low thermal expansion coefficient.įused Quartz Silica Glass transmits ultraviolet very well, making it useful for lenses and optics for the ultraviolet spectrum. It is the main component of most sand and the primary ingredient in glass. The synthetic fused silica glass AQ series is a high-purity, high-quality functional material based on AGCs abundant experience accumulated over its long. Often used in the same applications as fused silica, it has a significantly lower OH content. Silica makes up the mineral called quartz, and it is the most abundant mineral in the earths crust. It is used as a convenient source of sodium for many industrial products, as a builder in laundry. The 96 portion of SiO2 in the glass composition results in a. Excellent temperature resistance allows the use of this glass at high continuous operating temperatures of up to 900 C. Water glass is sold as solid lumps or powders or as a clear, syrupy liquid. The thermal properties of VYCOR 7913 from CORNING are comparable to those of quartz glass or fused silica, whereas VYCOR is significantly more economical. It differs from other glasses in the fact that no additional ingredients are required to lower the melt temperature, giving it much higher working and melting temperatures.įused quartz is developed by melting crystalline silica in sand or stone form. water glass, also called sodium silicate or soluble glass, a compound containing sodium oxide (Na2O) and silica (silicon dioxide, SiO2) that forms a glassy solid with the very useful property of being soluble in water. Fused quartz such as Fused Silica GE 124®, is a glass that can tolerate extreme temperature ranges and provide thermal shock resistance.
