摘要：
The preparation of glass-ceramics by utilizing the Wulong gold tailings as the main raw material was studied. According to chemical composition of the glass-ceramics, the formula for glass mixture and the nucleating agent were selected among MgO-Al2O3-SiO2 system from lattice constant, low melting-point and forming technology. The effects of glass composition and crystallization technology on crystallization properties of MgO-Al2O3-SiO2 system glass-ceramics were studied by means of DTA, XRD, polarizing microscope and SEM. The results show that glass-ceramics with good properties can be obtained, when some magnesia and aluminous raw materials and glass-network adjustment oxides are added. The predominant crystal phases of glass-ceramics are cordierite, spinel and enstatite.
