Quartz fiber has a series of unique advantages such as high strength, low dielectric constant and dielectric loss, high temperature resistance, small expansion coefficient, corrosion resistance, and good design performance. Quartz fiber applications include: missiles, airplanes, satellite radomes; satellites, warship antennas; electromagnetic windows (interference, anti-interference equipment) stealth technology structural materials (aircraft, warships, submarines); high-frequency printed circuit boards (portable phone technology) , Supercomputer); various high-temperature environment heat insulation: aircraft engine environment, fuselage fire barrier, thermal protection of space launch vehicles, heat insulation of rocket thrusters, etc.; automotive glass manufacturing industry; thermal insulation materials for semiconductor industry; high-temperature gas filtration; High temperature catalytic substrate; heat insulation material; replace silicate/asbestos fiber;

Chemical properties

Quartz fiber chemical stability applications: filter media for experimental analysis, filtration of hot acid gas, reinforcement of acid-resistant composites (if broken, the fiber is not corroded by chemical media). In addition to hydrofluoric acid and hot phosphoric acid, quartz glass has good acid resistance to general acids. At room temperature, alkali and salt corrode the quartz glass very slightly.
