摘要： The invention relates to porous bioglass and to the preparation method thereof. More specifically, the invention relates to a solid, porous crystalline or partially-crystalline composition containing at least SiO2, Ca O , Na2O, and P2O5, comprising micropores and macropores. The invention is characterised in that: the pore ratio varies between 50% and 80%, preferably between 60 and 75%, and is measured using the geometric method; the average diameter of the macropores varies between 100 and 1250 micrometers, preferably between 150 and 300 micrometers; the average diameter of the micropores is less than or equal to 5 micrometers; and the compression strength varies between 7 MPa and 70 MPa. The invention also relates to the method of preparing one such composition and to such a composition treated with a physiological liquid having an ionic composition similar to that of human plasma. The invention also relates to an implant which is made from one such composition.
摘要翻译：本发明涉及多孔生物玻璃及其制备方法。更具体地说，本发明涉及一种固体，多孔结晶或部分结晶组合物，其至少包含SiO 2，Ca 2 O 3，N 2 O 2 和P 2 O 5 O 5，包括微孔和大孔。本发明的特征在于：孔比在50％至80％之间变化，优选在60至75％之间，并使用几何方法测量; 大孔的平均直径在100和1250微米之间变化，优选在150和300微米之间; 微孔的平均直径小于或等于5微米; 压缩强度在7MPa〜70MPa之间变化。本发明还涉及制备一种这样的组合物的方法和用具有类似于人血浆的离子组成的生理液体处理的这种组合物的方法。本发明还涉及由一种这样的组合物制成的植入物。
