氧化物玻璃硬度不足导致耐磨性差的问题是制约玻璃产品高端化发展的瓶颈，传统的微晶化增硬工艺无法解决高析晶度和高光学透过率间的矛盾。本项目基于光的全反射原理，首次提出通过玻璃表面纳米改性和梯温热处理工艺、使玻璃表面原位生成具有高度定向排列特征的“类光纤结构”晶体阵列、从而获得高耐磨高光学透过率玻璃的新思路。高硬度晶体层确保玻璃表面耐磨性的提高，而“类光纤结构”形成的全反射则为降低光衰减提供保障。项目深入研究玻璃表面缺陷及断键离子与表面异质晶核间的相互作用，探索异质晶核成分、结构及形貌对玻璃表面析晶的影响规律，揭示玻璃在纳米改性和梯温热处理工艺下具有高度定向排列结构特征析晶层中晶体的原位生成机理，系统研究影响玻璃显微硬度和光学透过率的因素和调控方法，获得高硬度高透过率玻璃材料制备关键技术。本项目可突破传统透明微晶玻璃制备工艺的思维定势，深化透明微晶玻璃制备的理论基础，促进玻璃行业的技术转型升级。

The problem of poor wear resistance related to low hardness of glasses is a bottleneck the restricts the development of high-end glass products. The contradiction between high crystallinity and high optical transmittance cannot be solved by using the traditional crystallization hardening strategy. Based on the principle of total reflection of light, a new idea is proposed for the first time in this project, in order to obtain glasses with high wear-resistant and high optical transmittance, througth surface nano-modification of glasses and gradient heat treatment process. The high hardness of the crystal layer will ensure a high wear resistance of the glass surface, while the total reflection due to the "fiber-like structure" will guarantee the reduction of light attenuation. The project is aimed to intensively study the effects of glass surface defects and bond breaking ions on the surface heterogeneous nuclei behavior. The influence of composition, structure and morphology of the heterogeneous nuclei on crystallization of the glass surface will be explored. The in-situ formation mechanism of the crystals in the crystalline layer with highly oriented structures of glasses, due to the nano-modification and temperature-gradient heat treatment, will be clarified. As a consequence, a new technology to fabricate glasses with high hardness and high transmittance will be developed. The outcomes of this project will break through the mindset of traditional process to obtain transparent glass-ceramics, enrich the theoretical understanding on the formation of transparent glass-ceramics, and promote the technological transformation and upgrading of glass industries.
