Mineral fibres degradable in physiological medium. |
摘要 |
<p>Inorganic fibre compositions capable of being degraded in contact with a physiological environment. Advantageous compositions comprise the following constituents in the proportions by weight defined below: SiQ2 37 to 58 % Al2O3 4 to 14 % CaO 7 to 40 % MgO 4 to 16 % O2O5 1 to 10 % Fe2O3 0 to 15 % (total iron expressed in this form) the sum CaO + MgO + Fe2O3 remaining higher than 25 %, and the oxides Na2O and K2O, the sum of the percentages of which remains lower than 7%.</p> |
