摘要:

氧化铝陶瓷是第一个实现透明化的先进陶瓷材料, 拓展了先进陶瓷材料的研究和应用领域; 并作为高强度气体放电灯的关键部件——电弧管而获得实际应用. 近半个世纪以来, 人们在提高透过率的理论研究和优化制备工艺方面取得了众多成果. 本文对影响氧化铝透过率的本征因素进行分析, 综述了近年来透明氧化铝陶瓷发展的最新研究进展, 主要包括亚微米晶透明氧化铝、晶粒定向透明氧化铝以及固态晶体生长法获得氧化铝单晶三个方面, 最后展望了透明氧化铝陶瓷的发展趋势.

关键词: 透明氧化铝, 亚微米晶, 晶粒定向, 双折射, 固态晶体生长法

Abstract:

The first realization of transparent alumina ceramics among all advanced ceramics expand a new research field of advanced ceramics. The application of transparent alumina is also successful, such as arc tubes for high intensity discharge lamps. Fruitful results in theory research and processing optimization are made with the purpose of enhancing transmittance of alumina ceramics over the past half-century. In this paper, the effects of the intrinsic factors on the transmittance of alumina ceramics are studied. New methods and technology developments of transparent alumina reported in recent years are reviewed, mainly including sub-micrometer grain transparent alumina, oriented grain transparent alumina and single crystal alumina prepared by solid state crystal growth. The future tendency of transparent alumina ceramics are?also represented.

Key words: transparent alumina, sub-micron grain, oriented grain, bi-refraction, solid state crystal growth
