Quartz wool is widely used in high-temperature applications due to its excellent thermal stability and insulating properties. It is commonly employed as a thermal insulation material in furnaces, kilns, and other high-temperature environments where it helps to maintain consistent temperatures and reduce heat loss. Its resistance to thermal shock makes it ideal for use in laboratory settings, particularly in processes involving extreme heat or rapid temperature changes. Additionally, quartz wool is utilized in the filtration of corrosive gases and liquids, as it is chemically inert and can withstand harsh conditions. In the manufacturing of fiber optics, it serves as a protective layer to prevent damage during production. Its lightweight and flexible nature also make it suitable for packing and sealing in various industrial applications.
