    摘要： The invention relates to thermally-stable mineral wool which can dissolve in a physiological medium, comprising fibres containing the following constituents, expressed in percentage by weight, namely: 35-60 % SiO2, preferably 39-55 %; 12-27% Al2O3, preferably 16-25%; 0-35% CaO, preferably 3-25%; 0-30% MgO, preferably 0-15%; 0-17% Na2O, preferably 6-12%; 0-17% K2O, preferably 3-12%; 10-17% R2O (Na2O+K2O), preferably 12-17%; 0-5% P2O5, preferably 0-2%; 0-20% Fe2O3; 0-8% B2O3, preferably 0-4%; and 0-3% TiO2, and at least one phosphorous compound that can react with said fibres at a temperature of less than 1000° C. in order to form a coating on the surface thereof. The invention is characterised in that the phosphorous content of said compound, as expressed in phosphorus atom weight, varies between 0.0005%, in particular more than 0.01%, and 1%, in particular less than 0.5%, of the total weight of the fibres. The invention is also characterised in that a phosphorus compound is a molecule in which the phosphorus atom(s) are bound to at least one carbon atom either directly or by means of an oxygen atom.
