Effects of Glass Components Ratio on Structure and Properties of Baiyunebo Tailing Glass-ceramics

摘要：

　　Glass-ceramic in the CaO-MgO-Al2O3-SiO2 quaternary system was prepared using Baiyunebo tailing and fly ash as main raw materials by the method of melting.The processes of producing glass-ceramic included mixture,melting,molding,annealing,heat treatment,etc.The processing schedule for glass melting temperature,nucleation and crystallization temperature were chosen as 1450℃,720℃ and 850℃.The influences of glass components ratio on the structure were investigated by X-ray diffraction (XRD).It can be found that the main crystalline phase of augite,anorthite,magnesioferrite or magnetite mainly depended on glass components ratio.The results of mechanical measurements indicated that the bending strengths,density and chemical durability of glass-ceramics were concerned with the main crystal phase.The glass ceramics with augite phase had higher performance compared with others.
