Research on mixed alkaline-earth effect in non-alkali glass substrates for TFT-LCDs

Jianlei Liu et al.

Summary: In this study, we investigated the effect of mixed alkaline-earth effect on the structure and properties of non-alkali glass substrates by replacing MgO with CaO. The results showed that the stability of the glass network structure decreased with the replacement of CaO, and the comprehensive properties exhibited linear or nonlinear changes. The research findings provide important guidance for the property control of non-alkali glass substrates.

The structure and properties of chemical strengthened transparent lithium disilicate glass ceramics with various P2O5 contents

Tiehao Zhang et al.

Summary: Transparent lithium aluminosilicate glass-ceramics with nucleating agents of P2O5 and ZrO2 were prepared and their properties were investigated. The addition of a small amount of P2O5 improved the glass network structure and facilitated the conversion of Li2SiO3 to Li2Si2O5. The glass-ceramics exhibited high transmittance with the main crystalline phases of LiAlSi4O10 and Li2Si2O5. Chemical strengthening with NaNO3 and KNO3 resulted in enhanced hardness and fracture toughness.

Summary: The incorporation of nitrogen into oxide glasses can modify glass properties by changing glass polymerization and structure. This study investigates the compositional dependence of elastic properties and nanoindentation hardness of oxynitride glasses. The results show that the properties of the glasses are more influenced by the nitrogen content.

Summary: In this study, the K+-Na+ ion exchange was used to strengthen LAS glass-ceramic materials prepared by hot-pressing sintering. The XRD results and dissolution experiment confirmed the ion exchange mechanism and the improved chemical durability. The cellular experiments showed that the chemically strengthened LAS glass-ceramic had good biocompatibility, indicating its potential as dental restorative materials.

Mechanical, thermal, and structural investigations of chemically strengthened Na2O-CaO-Al2O3-SiO2 glasses

Stefan Karlsson et al.

Summary: In this study, the thermal, mechanical, and structural properties of soda-lime-silicate glasses were investigated before and after K+-for-Na+ ion-exchange strengthening. The increase in Al2O3 content resulted in increased glass network polymerization and decreased compactness. The pristine glasses showed an increase in T(g), H, and E(r) with increasing Al2O3 content, while the chemically strengthened glasses exhibited a linear dependence. Solid-state NMR revealed the presence of AlO4 groups in both types of glasses. The CS glasses had lower K+-for-Na+ ion exchange ratio compared to the soda-lime-silicate glass. Differential thermal analysis of CS glasses showed a blurred T(g) and an exothermic step below T(g). The hardness of the CS glasses at low loads and n(M O-(2))/n(Al2O3) & AP; 1 suggested increased elastic energy recovery and glass compactness.

Viviane O. Soares et al.

Summary: Glass-ceramics based on lithium metasilicate (LS) crystals were developed with a house-of-cards microstructure. The material exhibited favorable mechanical properties such as high fracture toughness and strength, as well as reasonable machinability, making it a promising candidate for dental restorative applications. Further optimization of its properties could enhance its suitability for various dental applications.

The influence of the mixed alkaline earth effect on the structure and properties of (Ca, Mg)-Si-Al-O-N glasses

Huili Wang et al.

Summary: The study successfully prepared alkaline earth oxynitride glasses with different CaO/(CaO + MgO) ratios and systematically analyzed their structural compositions and properties. The results showed that there were regular changes in static properties as the CaO/(CaO + MgO) ratio increased, while dynamic properties exhibited a mixed alkaline earth effect.

Structure-property relations in crack-resistant alkaline-earth aluminoborosilicate glasses studied by solid state NMR

Millena Logrado et al.

Summary: The study measured the effect of the average ionic potential of network modifier cations on crack initiation resistance and Young's modulus in alkaline-earth aluminoborosilicate glasses, correlating this with structural properties deduced from solid state NMR. The results suggest that in pure alkaline-earth boroaluminosilicate glasses, the trade-off between crack resistance and modulus can be adjusted by the alkaline-earth oxide inventory. Additionally, the presence of MgO in aluminoborosilicate glasses helps overcome the trade-off issue between high crack resistance and high elasticity modulus, offering new opportunities for designing glasses with both rigidity and crack resistance.
