  • Mineral fibres capable of dissolving in a physiological medium
    Patent number: 6060414
    Abstract: The present invention relates to mineral fibre composition which can dissolve in contact with a physiological medium. The composition of these fibres includes the following components, in accordance with the following proportions by weight:______________________________________ SiO.sub.2 48 to 67% Al.sub.2 O.sub.3 0 to 8% Fe.sub.2 O.sub.3 0 to 12% ______________________________________(total iron expressed in this form) ______________________________________ CaO 16 to 35% MgO 1 to 16% Na.sub.2 O + K.sub.2 O 0 to 6.5% P.sub.2 O.sub.5 0 to 5% ______________________________________taking into consideration that these compositions are also defined by the fact that the contents of these components comply with the following ratios:Na.sub.2 O+P.sub.2 O.sub.5 .gtoreq.2%Fe.sub.2 O.sub.3 +Al.sub.2 O.sub.3 .ltoreq.12%CaO+MgO+Fe.sub.2 O.sub.3 .gtoreq.23%.
