摘要
玻璃陶瓷(即微晶玻璃)由于原料易获取、易制备、性能兼具高硬度、高耐酸碱度等特点而在研究与应用领域备受瞩目。然而,其自身的脆性严重限制着该材料的服役表现。为解决这一问题,目前已能通过析晶增韧、相变增韧和纤维增韧三种主要方法显著提高玻璃陶瓷的韧性。旨在综述上述三种玻璃陶瓷增韧方法的基础上,展望未来可能的研究方向。为目前及将来相关领域的研究者规划相关研究方案提供参考和借鉴。
Glass ceramic,characterized by its good tolerance to composition variations,abundance of raw materials,easiness in fabrication and controllable properties,such as high hardness,and strong resistance to acid or alkaline corrosion,have attracted considerable attentions in both research and application fields.However,glass ceramic’s intrinsic brittleness has become the key obstacle to improving its performance and to expanding its applications.Therefore,researchers now have managed to improve the toughness of glass ceramics remarkably and successfully from the respects of crystallization,transformation toughening and fiber toughening.This paper will firstly review the mechanism and applications of these three major toughening techniques.Then,the remaining problems and possible directions for the future studies within this field will be outlined.This review can serve as a useful reference for now and future peers when they need to grasp a general idea on glass ceramic toughening techniques or to lay out plan for future researches.
