Abstract

The invention relates to a method of producing inorganic fibre products for heat insulating purposes, usable up to limit usage temperatures (LUT) of at least 750 DEG C up to approx. a maximum of 900 DEG C or as a substitute for asbestos in specific asbestos-containing products, preferably with a thermal loading. According to the invention, the high temperature resistance of this fibre product is achieved in that to produce the melt and the fibres to be produced therefrom, raw materials are used which contain the mineral "chlorite". Such fibres guarantee an extremely high dispersion of Fe<2+> and Fe<3+> ions in the melt and in the fibreglass.
