Abstract

ABSTRACT The lithium aluminosilicate system (LAS) is being explored for almost seven decades due to its anomalous and attractive properties (especially low/negative thermal expansion and fast ion conduction) and its commercial significance in consumer as well as strategic sectors. This review introduces current commercial applications of LAS systems, necessary background science, structural features of different LAS crystal systems, including their polymorphs and solid-solutions, and the origin of unusual properties. Significant emphasis is provided on processing transparent, nanocrystalline, low thermal expansion glass-ceramic (LEGC), the role of chemical constituents and additives, the effect of heat-treatment, and microstructural evolution while processing LEGC. Detailed discussions are provided on the following areas: LAS matrix composites, chemical strengthening of glass and glass-ceramic, low temperature co-fired ceramics (LTCC) and associated joining technologies (hydrolysis catalysis bonding, anodic bonding, brazing, etc.) that would further extend the application portfolio of LAS system.

铝硅酸锂（LAS）微晶玻璃研究进展

摘要铝硅酸锂系统（LAS）由于其异常和有吸引力的特性（特别是低/负热膨胀和快速离子传导）及其在消费和战略领域的商业意义，已经被探索了近70年。这篇综述介绍了LAS系统目前的商业应用，必要的背景科学，不同LAS晶体系统的结构特征，包括它们的多晶型和固溶体，以及不寻常性质的起源。重点介绍了加工透明、纳米晶体、低热膨胀微晶玻璃（LEGC）、化学成分和添加剂的作用、热处理的影响以及加工LEGC时的微观结构演变。详细讨论了以下领域：LAS基复合材料、玻璃和玻璃陶瓷的化学强化、低温共烧陶瓷（LTCC）和相关的连接技术（水解催化连接、阳极连接、钎焊等），这些技术将进一步扩展LAS系统的应用组合。
