Abstract

Abstract Bioactive glass is an emerging research area for many scientists around the world. A large processing window combined with high bioactivity are anticipated features for such kind of glass. In fact, both features depend upon the glass network connectivity (NC). A good bioactive glass has a network that ensures a balance between the processing properties and the bioactivity. This study aims at developing a new chemical composition based on that of ICIE16 bioactive glass. Therefore, new compositions were investigated by introducing boron oxide and magnesium oxide with different molar ratios ranging from 1 to 3 mol% each to the composition of ICIE16; In addition,Na2O was partially replaced by P2O5. Melt-quenching technique was followed to prepare the bioactive glass. So far, the results have shown that the processing window increases with the proposed modifications. BP3 and BM2 bioactive glasses show the maximum processing window of a round 250 K. The relationship between the chemical composition and the processing window as well as the corresponding bioactivity will be hereafter discussed.

提高加工性能的生物活性玻璃的化学成分精制，第1部分

摘要生物活性玻璃是当今世界许多科学家研究的一个新兴领域。大的加工窗口与高生物活性相结合是这种玻璃的预期特征。事实上，这两个功能都依赖于玻璃网络连接(NC)。良好的生物活性玻璃具有确保加工性能和生物活性之间平衡的网络。本研究的目的是在ICIE16生物活性玻璃的基础上开发一种新的化学成分。因此，在ICIE16中引入不同摩尔比(1 ~ 3mol %)的氧化硼和氧化镁，研究了新的化合物;此外，P2O5部分取代了Na2O。采用熔融淬火技术制备生物活性玻璃。到目前为止，结果表明，随着提出的修改，处理窗口增加。BP3和BM2生物活性玻璃的最大处理窗口约为250k。本文将讨论其化学成分与加工窗口的关系以及相应的生物活性。
