Abstract
Mineral fibers are provided with a phosphorus-containing coating to impart high-temperature resistance without substantially affecting mechanical performance. Preferred mineral-fiber compositions according to the invention with relatively high levels of SiO.sub.2 and low levels of Al.sub.2 O.sub.3 and Fe.sub.2 O.sub.3 compositions may advantageously be used for insulation. Such compositions have high-temperature resistance and high biosolubility, yet have properties which allow current processes to fabricate them into insulation. Preferably, the mineral fibers have a KI value.gtoreq.40.
