摘要

先进功能陶瓷逐渐成为许多高技术领域的关键材料,在很大程度上影响着其他产业的发展和进步,其中石榴石透明陶瓷受到工业化国家和科学家们的高度重视。虽然与石榴石陶瓷相关的文献已经很多,但比较全面的综述文章几乎没有。为了石榴石透明陶瓷朝着性能更优的方向发展,本文介绍了共沉淀、固相反应和溶胶凝胶法等陶瓷制备工艺,并对改进的工艺进行了比较。同时还分析了添加剂种类(TEOS和MgO等)及含量对陶瓷成型、烧结及性能的影响。除此之外,对石榴石透明陶瓷激光效率、发光、微波介电、磁光和闪烁性能等性能进行了相应的评述。

Abstract

Advanced functional ceramics have formed a group of key materials for many high-tech applications, strongly influencing the progress of other industries. Among various transparent ceramics, those with garnet structure have drawn increasing attentions by scientists in industrialized countries. Although garnet transparent ceramics have been covered in published articles, an overview on their progress has not been available, especially regarding to the achievements in recent years. This article was aimed to deliver an overview on the processing and applications of garnet transparent ceramics. The processing methods include solid-state reaction, chemical coprecipitation, sol-gel process and so on. The effects of additive (TEOS and MgO, etc.) were also discussed. For certain applications, their performances will be elaborated in terms of the parameters, such as laser efficiency, luminescent effect, microwave dielectric behavior, magneto-light effect and scintillation.

Key words: Garnet; Transparent ceramics; Coprecipitation; Solid state reaction; Light transmittance; Phosphor; Laser efficiency; Magneto-optical effect; Scintillator
