Abstract

Rare earth-free Na₅RSi₄O₁₂-type sodium-ion conductive glass-ceramics (R: rare earth elements) were successfully synthesized through the crystallization of glasses using the composition Na_5+xFe(B_xSi_4-x)O₁₂ (x = 0–0.5). Differential thermal analysis was used to examine the glass-crystallization kinetics, providing insight into boron's effects on phase separation and its subsequent microstructural influence on the conduction properties of the glass-ceramics. The activation energy for crystal growth in Na_5.2FeB_0.2Si_3.8O₁₂ (x = 0.2) was determined to be 440 kJ mol⁻¹. These glass-ceramics exhibited an ionic conductivity of 3.05 × 10⁻³ S cm⁻¹ at 300 °C, with an activation energy of 48.5 kJ mol⁻¹.

期刊介绍： Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties. Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour. Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
