Quartz wool is widely used in high-temperature insulation applications due to its excellent thermal stability and resistance to heat. It is commonly employed in furnaces, kilns, and other industrial heating equipment to provide effective insulation and maintain energy efficiency. Additionally, quartz wool is utilized in laboratories as a filtering medium for corrosive or high-temperature gases and liquids, thanks to its chemical inertness. In the manufacturing of semiconductors and optical fibers, it serves as a protective material during high-temperature processes. Its lightweight and flexible nature also make it suitable for sealing and packing in various industrial applications.
