Sol-gel Bioactive Glass Initial Solution And A Preparation Method Of The Sol-gel Bioactive Glass And The Prepared Sol-gel Bioactive Glass Initial Solution

Abstract

A kind of sol-gel bioactive glass initial solution and a preparation method of the sol-gel bioactive glass and the prepared sol-gel bioactive glass initial solution are mentioned. The method includes Na2O is leaded into a glass network via using Na-ethoxide (C2H5ONa)or NaC1 but not sodium nitrate in the process of sol-gel. The kind of glass has the medical application and the industrial use.

Description

technical field [0001] The present invention generally includes novel sol-gel prepared sodium-containing bioactive glasses and their uses. Background technique [0002] The sol-gel process for the preparation of bioactive glasses using the sol-gel technique is generally well known. For example, U.S. Patent No. 5,074,916 (the "'916 patent"), the subject matter of which is incorporated herein by reference, discloses methods for producing SiO-based 2 , CaO 2 and P 2 o 5 Sol-Gel Processing Technology of Alkali-Free Bioactive Glass Compositions. The '916 patent discloses that by changing the SiO 2 content, a series of compositions with different degrees of hydroxyapatite generation rate can be obtained. Furthermore, changing the response time to real or simulated in vivo solutions expands the available composition of SiO 2 proportion. The sol-gel prepared compositions disclosed in the '916 patent can be selected to achieve target values ​​for thermal expansion coefficient...
