  • Quartz fiber - Wikipedia

    Since quartz fiber is expensive, it has limited applications. It is used mainly for producing composite materials (due to having higher stability compared to glass fiber) and in electrical applications where thermal resistance and dielectric properties are important. It can be used in filtration applications where alternatives such as glass fiber filters cannot be used.
