“…In recent years, the solid-state sodium-ion rechargeable batteries have gained wide attention due to abundant sodium sources, impressive energy densities reaching up to 760 Wh kg -1 and their applicability in distributed power systems for storing renewable energy [1][2][3]. Addressing safety concerns, all solidstate batteries leverage solid inorganic electrolytes instead of liquid organic electrolytes, mitigating issues such as leakage, volatilization and flammability [4,5]. To achieve high ionic conductivity, researchers are focusing on the development of sulfide-based glasses and glass-ceramics as solid electrolytes [6][7][8].…”

In the present investigation, a glass-ceramics with the composition of xNa2S + (100–x)P2S5, where x = 40, 45, 50 and 55, were successfully synthesized by employing the melt-quenching method. Comprehensive characterization of the glass-ceramic samples was conducted using X-ray diffraction (XRD), UV-visible spectroscopy, impedance spectroscopy (IS) and field emission scanning electron microscopy (FE-SEM) techniques. The XRD analysis revealed the presence of three distinct phases, namely NaPO3, Na2S2O3 and Na3PS4, in all samples. Significantly, NaPO3 and Na2S2O3 exhibited an orthorhombic crystal structure, while Na3PS4 displayed a tetragonal crystal structure. The densities of the synthesized samples fell within the range of 2.24 to 2.35 g/cc, surpassing those of Li2S-based solid electrolytes commonly used in portable devices. The band gap of the materials varied from 2.99 to 3.60 eV. Significantly, an inverse relationship between Na2S content (modifier) and band gap was observed, indicating a decrease in band gaps with increasing Na2S content. This phenomenon is beneficial for enhancing ionic conductivity. At ambient temperature, samples with x values of 50 and 55 demonstrated remarkable conductivity on the order of 10-4 S cm-1. Overall, the synthesized glass ceramics exhibit promising features, such as higher density compared to conventional Li2S-based solid electrolytes and favourable band gap values, suggesting their potential application in enhancing ionic conductivity for various electronic devices.

“…Furthermore, the kinetic analysis is crucial to understand the thermal behavior of material at elevated temperatures . Several researchers performed kinetic analysis for a variety of materials such as polymers, ceramics, metals, and biomass through thermogravimetric analysis (TGA), the differential thermal analysis (DTA), and differential scanning calorimetry (DSC) . They calculated kinetic triplets (activation energy, pre‐exponential factor, reaction mechanism) by following different kinetic methods.…”

Nanocrystalline molybdenum disilicide (MoSi2) is synthesized in a specially designed autoclave at 900°C. The XRD results revealed that the formation of MoSi2 is favorable with the blend of MoO3, Si, and Mg powders. The HR‐TEM and SAED patterns confirm the formation of MoSi2 phase. The structural parameters (crystallite size, strain, stress, and deformation energy density) are calculated using the Williamson‐Hall (W‐H) analysis. The formation mechanism involved in the synthesis of MoSi2 is proposed. The nonisothermal oxidation kinetics (~1200°C) of MoSi2 phase is examined through the thermal analysis techniques. The activation energy is determined by the Kissinger‐Akahira‐Sunsose isoconversional kinetic model. Finally, the reaction mechanism involved during the oxidation of MoSi2 phase is identified using the integral master‐plots method.
