In this study, chlorinated bioactive glasses were synthesized via a hydrolytic sol–gel route using tetraethyl orthosilicate (TEOS) and calcium chloride, aiming to obtain materials with efficient ionic release and controlled pH response. Samples were thermally treated at 500 °C, 600 °C, and 700 °C and characterized by FTIR, Raman spectroscopy, specific surface area (BET), scanning electron microscopy (SEM), and ionic release tests. The chlorinated bioactive glass calcined at 500 °C exhibited the most promising combination of characteristics: presence of hydroxyl groups (–OH), a structure predominantly composed of Q² units, high specific surface area (31.75 m² g⁻¹), well-defined mesoporosity, high ionic release (∼2000 µS cm⁻¹), and effective control of pH increase in aqueous media. These properties directly contribute to bioactivity and indicate that this material can be incorporated into biomedical formulations without the need for prior neutralization steps, in contrast to many conventional bioactive glasses. The results also demonstrate that the hydrolytic sol–gel route enables the synthesis of chlorinated bioactive glasses with tunable structure and dissolution profiles, overcoming limitations associated with more complex routes, such as those based on ion-exchange resins or precursors like metasilicate.

Due to the small size of the cells, the variation between the mean and fluctuating values of energy is comparable to their van der Waals bond energy. As a result, each cell fluctuates between the glassy and elastomeric state. The period of phase fluctuation, designated τ, varies from cell to cell. The values of τ increase with a decrease in temperature, causing the glass transition.

This study employed a multi-step heat treatment protocol to fabricate a series of Li<sub>2</sub>O-Al<sub>2</sub>O<sub>3</sub>-SiO<sub>2</sub> (LAS) glass-ceramic (SL1-SL6) samples with varying metal oxide contents. Research indicates that increasing the SiO<sub>2</sub> content while reducing the Li<sub>2</sub>O content in LAS glass-ceramics can modulate the abundance of the α-tridymite phase, thereby optimizing a spectrum of properties, including enhanced toughness and improved dielectric performance. Experimental results demonstrate that when the SiO<sub>2</sub>/Li<sub>2</sub>O mass ratio increases to 6.69 (SL6), the glass-ceramic achieves permittivity as low as 5.266 and loss tangent of 7.23×10<sup>−3</sup>. Concurrently, SL6 also exhibits a high elastic modulus (99.7 GPa) and fracture toughness (1.90 MPa·m<sup>1/2</sup>). Furthermore, SL6 possesses CTE of 11.322×10<sup>−6</sup> K<sup>−1</sup> (50∼500 °C). The adoption of a multi-step heat treatment protocol coupled with compositional adjustments proves effective in refining the properties of glass-ceramics, offering technical support for realizing low-cost, high-performance chip packaging substrates.</div></div>","PeriodicalId":16461,"journal":{"name":"Journal of Non-crystalline Solids","volume":"673 ","pages":"Article 123870"},"PeriodicalIF":3.5,"publicationDate":"2026-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145532676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
