MAS transparent glass ceramics with high crystallinity is expected to become another key engineering materials similar to Zerodur glass ceramics made in German due to its excellent comprehensive performance.Also it is possible that this glass-ceramics replace transparent crystal and ceramics which are difficult to prepare by the domestic and foreign existing technology and equipment.The controllable preparation and performance regulation technique of MAS transparent glass ceramics with high crystallinity will be mainly studied in this project.The nucleation and crystal growth mechanism of MAS system basic glass will be explored by thermodynamic calculation according to JAM (Johnson-Mehl-Avrami) and Ozawa model.The correlation between rare earth ions and glass formation and crystallization behavior will be revealed. The property dependence of MgO-Al2O3-SiO2 transparent glass ceramics will be widely studied for finding their change regulation with composition , process and structure. The physico-chemical performance index system will be established .The aim is to provide theoretical basis and technical support in order to realize the controllable preparation, performance pruning and application development of MAS transparent glass ceramics with high crystallinity. The research will promote the progress of preparation science and technology progress of MAS transparent glass ceramics with high crystallinity by enriching and developing the glass melting technology, nucleation and crystallization theory and performance evolution rules.Obviously,the research has a very important scientific significance and theoretical value. At the same time, the successful development of MAS transparent glass ceramics with high crystallinity has great practical value because it will increase new kind of optical functional materials , meet the needs of our national economic construction and social development for key engineering materials and form the brand made in China.
