Chemical Composition Refining of Bioactive Glass for Better Processing Features, Part I

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.
