釉面耐磨性不足的问题已成为制约陶瓷产品高端化发展与产业转型升级的瓶颈。本项目将玻璃科学与陶瓷科学交叉融合，采用高析晶度透明微晶熔块作为陶瓷釉料以提高其耐磨性。针对建筑陶瓷快速烧成条件下晶核在短时间内难以大量形成、析晶后釉面光学透过率低等问题，突破传统熔块釉均质配料的思维定势，首次提出利用两种始熔点不同、但组成与折射率相近的混合熔块共同作为釉料的新思路。深入研究混合熔块在高温下透明非晶界面的形成过程及对降低晶核成核势垒的影响机制，揭示界面能与界面附近浓度起伏对促进晶核形成的作用机理，探讨冷却过程中晶化温度场微扰动形成的热起伏对微晶熔块结构演变的影响规律，探索微晶熔块中晶相与玻璃相折射率的双向可控调节原理，获得高析晶度高透过率微晶熔块制备关键技术，显著提高陶瓷釉面耐磨性。本项目将突破陶瓷界对传统熔块釉的认知与利用局限，深化透明微晶熔块釉制备的基础理论，促进高性能微晶釉料在陶瓷材料中的推广应用。

The weak mechanical abrasion resistance of glazed ceramic has become a key bottleneck to restrict the high-end oriented development of ceramic products and the corresponding industrial upgrading. This project will combine glass and ceramic science, being aimed to improve the abrasion resistance of ceramic glaze by utilizing a highly crystalline transparent glass-ceramic frit as ceramic glaze. It is difficult to form a large number of nuclei in a short time for the rapid firing of building ceramics, and the optical transmission rate of crystallization glaze is hard to improve. In order to solve these problems, the traditional mindset of homogeneous ingredients of frit glaze is broken and a new idea that two frit glazes with different initial melting points but similar composition and refractive index mixed together is first proposed in this project. This project will focus on the formation process of transparent amorphous interfaces in mixed frit at high temperature and the influence mechanism of the interfaces reduced the nucleation barrier. The influence mechanism of the interfacial energy and the fluctuation of the concentration near the interface on the formation of crystal nucleus will be revealed. To obtain the key technologies to preparation a ceramic frit with highly crystalline and high transmittance, the effect of thermal fluctuation of crystallization temperature perturbation during cooling process on the evolution of micro-structure and the controllable regulation principle of refractive for crystal and glass phase in mixed frits will be intensively studied. This project is expected to break through the limitations of available knowledge and application on traditional fritted glaze for building ceramic tiles, to deepen the theoretical basic of the transparent glass-ceramic frit, and to promote the wide application of the developed highly crystalline glass-ceramics as ceramic glaze products.
