“…However, some additional elements are highly beneficial for tailoring the bioactive and even biological response of the material (therapeutic effect). For example, CaO and MgO were reported to play an important role in surface reaction kinetics, new bone formation and bone cell adhesion and stability [24][25][26]. Silver was also incorporated in sol-gel SiO 2 -CaO glasses to obtain foam-like scaffolds with antibacterial properties [27].…”

Bioactive sol-gel glasses are attractive biomaterials from both technological and functional viewpoints as they require lower processing temperatures compared to their melt-derived counterparts and exhibit a high specific surface area due to inherent nanoporosity. However, most of these materials are based on relatively simple binary or ternary oxide systems since the synthesis of multicomponent glasses via sol-gel still is a challenge. This work reports for the first time the production and characterization of sol-gel materials based on a six-oxide basic system (SiO2–P2O5–CaO–MgO–Na2O–K2O). It was shown that calcination played a role in inducing the formation of crystalline phases, thus generating glass-ceramic materials. The thermal, microstructural and textural properties, as well as the in vitro bioactivity, of these sol-gel materials were assessed and compared to those of the melt-derived counterpart glass with the same nominal composition. In spite of their glass-ceramic nature, these materials retained an excellent apatite-forming ability, which is key in bone repair applications.

“…Some oxides such as TiO 2 enhance the mechanical properties without harming bioactive properties. TiO 2 is an intermediate oxide; thus, due to higher bonding energy of Ti–O bond as compared to modifiers (alkali/alkaline earth metal oxides), the glasses with TiO 2 exhibit better network connectivity which improves their mechanical properties . It has also been reported that TiO 2 improves the glass forming ability as well as wettability of the glasses which leads to better bioactivity of the glasses .…”

We report on the structural, magnetic, and bioactive properties of TiO2‐modified silicate glasses. Addition of TiO2 and heat treatment, shows remarkable and distinguishable effect on the properties of the glasses. Growth of titania‐modified magnetic nanocrystals played effective role in the evolution of magnetic properties of the glass‐ceramics. Some of the samples exhibit superparamagnetic nature, while others are found to be antiferromagnetic. Interestingly, after heat treatment the magnetization trend of the samples reversed. The in vitro bioactivity of these glass‐ceramics was accessed by the formation of bone‐ like apatite structures on their surfaces after immersion in simulated body fluid. The magnetic properties along with the bioactivity of present glass‐ceramics indicate their usefulness in the magnetically induced hyperthermia treatment of cancer.

“…One approach to increasing these properties is to add various oxides to phosphate glasses, such as PbO, MgO, and TiO 2 , and MnO, etc. These oxides lead to the formation of Pb-O-P, Mg-O-P, Ti-O-P and Mn-O-P bonds which replace the easily hydrolysable P-P-P bonds and improve dramatically the chemical durability of the modified phosphate glasses [9][10][11][12][13]. Similarly, the properties of these glasses in terms of mechanical, structural, and electrical properties can be also improved by adding some oxides cited MATEC Web of Conferences 149, 01081 (2018) https://doi.org/10.1051/matecconf/201814901081 CMSS-2017 above.…”

Abstract. Homogeneous phosphate glasses having the general formula 20K 2 O-xMnO-(80-x)P 2 O 5 were synthesized using a melt-quenching method. The amorphous nature of the samples was asserted by X-ray diffraction. The glasses are studied in order to evaluate the influence of MnO addition on the chemical and mechanical properties, such as, dissolution rate, average compressive strength (Rc), Young's modulus (E) and limit strain (Ɛ lim ). Some studies show that the addition of MnO significantly reduces the degradation rate (D R ) of soluble phosphate glasses and enhanced chemical stability of both alkali-resistance and acid-resistance. MnO interfere with the chemical structure of the glass, and consequently improve their mechanical properties. Indeed, the mechanical measurements showed that the glass structure was modified by the addition of MnO oxide, becoming more rigid, and as a result, increasing the compressive strength (Rc), Young's modulus (E). These new materials could be an important opportunity for applications in the fields of building, construction, civil engineering, etc…
