A type of fiberglass filter media satisfying the use in nuclear power stations has been developed. The key technology is the finish for the filter media, which can prevent or reduce the leach-out of SiO_2 in aqueous solutions of boric acid and lithium hydroxide. Blank paper for such filter media is made from glass fibers using the proprietary wet process, finished with a precious additive, and after drying, laminated with organic fiber layers on both sides for protection. The filter media have been successfully used in a nuclear power station in Pakistan.
