摘　　要：微晶玻璃是一种由基础玻璃经可控热处理而得到的具有一定晶相含量及部分残余玻璃相的新型材料,与相同组成的陶瓷材料具有类似的显微结构,但由于微晶玻璃在制备过程中很容易实现零气孔和全致密,因而微晶玻璃可获得比陶瓷更为优异的综合性能。大部分微晶玻璃析晶后均为不透明状态,通过控制晶体尺寸及含量,或通过组成设计对析出晶体的折射率进行调节,部分体系的微晶玻璃可实现半透明甚至高透明。由于透明微晶玻璃既具有玻璃在成型和光学性能方面的优势,又具有陶瓷在机械性能和稳定性等方面的优点,因而在军事、工业生产、生物技术、日常生活等领域得到了广泛的应用。系统介绍了微晶玻璃的透明机理、组成体系及制备工艺,并对Li_(2)O-Al_(2)O_(3)-SiO_(2)、MgO-Al_(2)O_(3)-SiO_(2)、ZnO-Al_(2)O_(3)-SiO_(2)等体系透明微晶玻璃研究进展及应用现状进行了深入讨论。Glass-ceramics consist of a certain content of crystalline phase in residual glass phase obtained from the glasses through controlled heat treatment.It has a similar microstructure with ceramic materials of the same composition.However,because glass-ceramics could have zero porosity and full density,they have superior properties than the conventional ceramics.Most glasses are opaque after crystallization.By controlling the crystal size and content or adjusting the refractive index of the precipitated crystals through composition design,glass-ceramics of some systems could have translucency or even high transparency.Transparent glass-ceramics are widely used in military,industrial production,biotechnology,daily life and other fields,because they have the advantages of both glass in molding and optical properties and ceramics in mechanical properties and stability.Transparent mechanism,composition system and preparation process of glass-ceramics are systematically introduced,while the research progress and application status of Li_(2)O-Al_(2)O_(3)-SiO_(2),MgO-Al_(2)O_(3)-SiO_(2),ZnO-Al_(2)O_(3)-SiO_(2) and other transparent glass-ceramics are discussed in depth.
