Preparation of Reference Material for Component Analysis of High Silica Glass Fiber

A reference material used for the component analysis of high silica glass fiber is prepared by the high-temperature melting process, a technique that can ensure the homogeneity and stability of each component. With two methods based on different principles, the components in glass fiber are accurately characterized through the joint efforts of multiple laboratories. The results show that the reference material was accurately and reliably characterized and exhibited good homogeneity and stability, and that the expanded uncertainty of the standard values was 5%-10% ( k =2). Therefore, the reference material can be used to evaluate component testing methods for high silica glass fiber and calibrate related analytical instruments so that the accuracy and reliability of component characterization are ensured.
