<p>The submitted invention refers to the compositions of mineral fibres that are degradable in the contact with the physiological medium. The preferential compositions include the following components with the following mass proportions defined below: SiO2 - 37 to 58 %, Al2O3 - 4 to 14 %, CaO - 7 to 40 %, MgO - 4 to 16 %, P2O5 - 1 to 10 %, Fe2O3 - 0 to 15 % (total iron expressed in this form), where the sum of CaO + MgO + Fe2O3 exceeds more than 25 %, as well as the oxides Na2O and K2O which do not exceed 7 %.</p> |
