摘要
云母微晶玻璃是一种独特的玻璃陶瓷复合材料,一般通过对K2O-MgO-MgF2-Al_(2)O_(3)-SiO_(2)体系玻璃进行热处理而获得,这一过程使其主要以云母晶体为主晶相,形成具有特殊片层状结构的微晶玻璃。系统地介绍了云母微晶玻璃的组成体系、制备方法,以及其微观结构与性能的研究进展,特别关注的是其独特的可切削性能,其层片状结构为其赋予了出色的可切削特性,使其能够通过各种加工手段制成精密尺寸、精密配合和复杂形状的构件。重点总结了云母微晶玻璃在生物组织、高精度结构件、真空电子器件等领域展现出是卓越的应用能力,并对云母微晶玻璃的发展趋势进行了展望。
Mica glass-ceramics is a composite material composed of lamellar or needle-shaped mica crystals and a glass phase.It originates from the K_(2)O-MgO-MgF_(2)-Al_(2)O_(3)-SiO_(2) system,which has been developed by incorporating various additives.This process makes the mica crystal as the main crystal phase,forming glass-ceramics with special lamellar structure.The progress in composition system,preparation method,properties and applications of mica glass-ceramics are systematically introduced.Special attention is paid to their unique machinable properties.Their lamellar structure gives it excellent machinable characteristics,enabling it to be made into components with precise size,precise fit and complex shape by using various processing means.Mica glass-ceramics exhibit applications in the fields of biological tissue,high-precision structural parts,vacuum electronic devices,etc.Finally,the development trend of mica glass-ceramics is prospected.
