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 maintain temperature efficiency and protect surrounding components from extreme heat. Additionally, it serves as a filtration medium in environments requiring chemical inertness, such as in laboratories or industrial processes involving corrosive substances. Its lightweight and flexible nature also make it suitable for packing and sealing in high-temperature systems, ensuring minimal heat loss.
