Abstract
Commonly believed, glass is more chemically durable than the majority of other materials. However, corrosion occurs when a glass piece is exposed to a liquid solution. This study investigates the durability and mechanical properties of zinc tellurite glasses as a function of their chemical composition for different oxide modifiers (Na2O, B2O3, CaO, and P2O5). Glasses systems based on 60TeO2-30ZnO-10Na2O (TZN), 75TeO2-10ZnO-15 B2O3 (TZB), 70TeO2-10ZnO-20CaO (TZC) and 75TeO2-15ZnO-10P2O5 (TZP) reported here were prepared by melt-quenching technique. The amorphous nature of the prepared glasses is tested using the X-ray diffraction (XRD) technique. The glasses' hardness (HV) and tensile strength were examined by microhardness Vickers's indentation. Phosphate as an oxide modifier content significantly impacts the glass's hardness, TZP glass possesses the highest hardness, 698.7 HV. The chemical durability of the glass was performed by immersing it in a sulfuric acid solution with a pH of 2 for 15 days. Microstructural characterization was performed using scanning electron microscopy (SEM) to study the morphology and structural changes of the glass samples. The attractive characteristics of chemical stability and enhanced mechanical properties suggest that the TZP glass can be designated as a suitable host for long-life optoelectronic applications that perform well in various environments.
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.
