Quartz wool is widely used in high-temperature applications due to its excellent thermal stability and insulating properties. It is commonly employed as insulation material in furnaces, kilns, and other industrial heating equipment to maintain high temperatures efficiently. Its resistance to thermal shock makes it ideal for use in environments with extreme temperature fluctuations. Additionally, quartz wool is utilized in the production of fiber optic cables, where its purity and low thermal expansion are critical for maintaining signal integrity. In laboratories, it serves as a filtering medium for corrosive or high-temperature gases and liquids, and is specially suited for elemental analyzers with fiber diameters of 1-3 μm. Its inert nature also makes it suitable for use in chemical processing and semiconductor manufacturing, where contamination must be minimized.
