英文摘要： It is a high value-added and ecological way to prepare glass-ceramics by using the metallurgical solid secondary resources. The group is going to focus on the research of preparing high-performance glass-ceramics with the starting materials of main steel slag and other metallurgical solid wastes based on previous study. The contents of this project contain: (1) The components and structure characteristics of metallurgical solid wastes will be studied by DSC, XRD, XRF, polarizing microscope image-analyzer, and other research techniques. The feasible of preparing of glass-ceramics with different kinds and proportions of metallurgical materials will also be analyzed. (2) On one side of external strengthening, the steel slag basing glass-ceramics system will be studied with the assistance of FactSage software and atlas. The important parameter of special sintering will also be discussed in detail in present program. (3) On the other side of internal strengthening, the rules of secondary extracting ferrum and coefficient of the three agents will be founded through the analysis of microscopic behaviors of nucleant, modifier and reinforcer. The parameters of thermal treatment, glass matrix, crystal component, microstructure effects on the crystallization and mechanical properties will be studied by TEM, EDX, FTIR, Raman, etc. This results will also provide more information for the study of kinetics. In conclusion, this program will provide fundament theories and research methods on preparing of high-performance glass-ceramics by using the metallurgical solid wasters and also provide a direction and support on the preparing of ceramic materials with the same staring materials.
