Basic glass with stable properties was prepared from molten blast furnace slag by using the melting method. The heat treatment regime of glass-ceramics was determined by differential thermal analysis of the basic glass. Optimum heat treatment parame-ters were selected and the crystal growth pattern of glass-ceramics was analyzed by X-ray diffraction and scanning electron microscopy. The results show that the optimum heat treatment parameters of glass-ceramics are the nucleation temperature of 850℃for 1. 5 h and the crystallization temperature of 935℃ for 1 h. The crystallization grows from the surface to interior gradually. The mechanical properties of the prepared glass-ceramics, such as bending strength, acid and alkali resistance, and hardness, are better than those of ordinary marble.
