Structure and Properties of Molten Blast Furnace Slag Glass-Ceramics
摘要
Abstract
Molten slag has a large amount of heat and slag.The preparation of glass-ceramics by melting method using molten slag can utilize the furnace slag efficiently.The parent glass with stable performance was prepared by mixed-melting at high temperature.The heat treatment process of the parent glass was determined by differential scanning calorimetry (DSC).The microstructure and properties of the glass-ceramics were characterized by transmission electron microscope (TEM), X-ray diffraction (XRD), scanning electron microscopy (FE-SEM).The results indicate that the increase of F content in the parent glass promot the nucleation and crystal growth and decrease the nucleation and crystallization temperature of the glass ceramics.The main crystal phase of glass-ceramics is fluorite at the low heat treatment temperature, nepheline and fluorite are precipitated simultaneously at high heat treatment temperature.The content and type of crystalline phase significantly influence the flexural strength and hardness of the glass-ceramics, the microhardness is up to 585.68 MPa, the flexural strength is up to 126.21 MPa.关键词
