Abstract

Melt-quenching bioglass-ceramics with the following chemical composition have been prepared 44SLS\( -\)11Na₂CO₃\( -\)24ES\( -\)6P₂O₅\( -\)6CaF₂\( -\)9Al₂O₃ (wt%). The bioglass-ceramics were sintered at 650 °C, 750 °C, 850 °C, and 950 °C. The aim was to identify the optimal sintering temperature before glass crystallization. The physical properties were characterized by density and linear shrinkage. To characterize the structure properties, X-ray diffraction (XRD), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR) were utilized. The high composition of Si and Ca in soda lime silica (SLS) glass and eggshells (ES), respectively, encourage the utilization of waste materials in the production of bioglass-ceramics. The results showed that at a sintering temperature of 950 °C, the crystallization of fluorapatite was the main phase. Moreover, the high density and optimum linear shrinkage were obtained as the sintering temperature increased. Additionally, grain growth and densification took place at this temperature. The compressive strength of bioglass-ceramics is influenced by sintering temperature and the optimal compressive strength is 136.58 MPa.

温度变化对基于 SLS-Na2CO3-ES-P2O5-CaF2-Al2O3 的生物玻璃陶瓷制造的影响

制备了具有以下化学成分的熔淬生物玻璃陶瓷 44SLS\( -\)11Na2CO3\( -\)24ES\( -\)6P2O5\( -\)6CaF2\( -\)9Al2O3 (wt%)。生物玻璃陶瓷分别在 650 ℃、750 ℃、850 ℃ 和 950 ℃ 下烧结。目的是确定玻璃结晶前的最佳烧结温度。物理性质通过密度和线性收缩率来表征。为了表征结构特性，使用了 X 射线衍射 (XRD)、扫描电子显微镜 (SEM) 和傅立叶变换红外光谱 (FTIR)。苏打石灰二氧化硅（SLS）玻璃和蛋壳（ES）中的硅和钙含量分别很高，这有助于利用废料生产生物玻璃陶瓷。结果表明，在 950 °C 的烧结温度下，氟磷灰石是主要的结晶相。此外，随着烧结温度的升高，可获得高密度和最佳线性收缩率。此外，晶粒生长和致密化也在该温度下发生。生物玻璃陶瓷的抗压强度受烧结温度的影响，最佳抗压强度为 136.58 兆帕。
