Abstract

This article investigates the development and potential applications of low-melting point lead-free glasses. Their importance is due to strong market demands to comply with the strict international regulations against the use of lead. In this work, a preliminary study of the existing interactions of a low-melting-temperature glass belonging to the P₂O₅–CaO–Na₂O system when it is deposited on different ceramic substrates, both traditional (porcelain stoneware) and technical (alumina and zirconia), has been carried out. The ionic diffusion through the studied interfaces, the phases present, the composition of the glassy phase and the surface morphology of the coating have been studied by Field Emission Scanning Electron Microscopy (FESEM), with coupled EDX microanalysis. The chemical resistance of the different glassy coatings obtained is also evaluated. The results showed that these new lead-free low-melting-temperature glassy coatings are chemically and mechanically compatible, and promising candidates for applications and markets in a broad range of fields.

属于P2O5–CaO–Na2O系统的低熔融温度玻璃，用作工业陶瓷（氧化铝、氧化锆）和传统陶瓷（陶瓷石）的涂层

本文探讨了低熔点无铅玻璃的开发和潜在应用。低熔点无铅玻璃之所以重要，是因为市场强烈要求遵守禁止使用铅的严格国际法规。在这项工作中，我们对属于 P2O5-CaO-Na2O 系统的低熔点玻璃沉积在不同陶瓷基底（传统陶瓷（炻瓷）和技术陶瓷（氧化铝和氧化锆））上时的现有相互作用进行了初步研究。通过场发射扫描电子显微镜（FESEM）和耦合 EDX 显微分析，研究了通过所研究界面的离子扩散、存在的相、玻璃相的组成和涂层的表面形态。此外，还对不同玻璃涂层的耐化学性进行了评估。结果表明，这些新型无铅低温熔融玻璃涂层在化学和机械方面都具有良好的兼容性，有望在广泛的领域中得到应用和市场。

期刊介绍： The Journal of the Spanish Ceramic and Glass Society publishes scientific articles and communications describing original research and reviews relating to ceramic materials and glasses. The main interests are on novel generic science and technology establishing the relationships between synthesis, processing microstructure and properties of materials. Papers may deal with ceramics and glasses included in any of the conventional categories: structural, functional, traditional, composites and cultural heritage. The main objective of the Journal of the Spanish Ceramic and Glass Society is to sustain a high standard research quality by means of appropriate reviewing procedures.
