摘　　要：为解决硅锰渣堆积的问题,以硅锰渣为原料通过一步烧结法制备出耐酸性能优异的微晶玻璃。探究了MgO对微晶玻璃物理性能、微观形貌和晶形结构的影响,采用正交实验探究了合适的CaF_(2)添加量以及烧制温度。采用X射线衍射(XRD)和扫描电镜(SEM)等手段对试样的物相和微观形貌等进行了表征。结果表明:MgO含量的增加有利于促进液相的形成并提高试样的综合性能。所制备的微晶玻璃具有较高的密度(2.69g/cm^(3)),良好的耐酸性(97.6%)和较高的抗压强度(368MPa)。研究为硅锰渣制备高耐酸微晶玻璃提供了科学的理论数据,同时拓宽了硅锰渣利用途径。In order to solve the problem of silicon manganese slag accumulation,this study prepared glassceramics with excellent acid resistance using silicon manganese slag as the raw material through a onestep sintering method.The effects of MgO on the physical properties,microstructure and crystal structure of glass-ceramics were investigated.Additionally,the appropriate amount of CaF_(2) and firing temperature were investigated by orthogonal experiments.The phase and morphology of the samples were characterized by X-ray diffraction(XRD)and scanning electron microscopy(SEM).The results show that the increase in MgO content can promote the formation of liquid phases and improve the comprehensive properties of the samples.The prepared glass-ceramics have high density(2.69 g/cm^(3)),good acid resistance(97.6%)and high compressive strength(368 MPa).This study provides scientific theoretical data for the preparation of high acid-resistant glass-ceramics from silicon manganese slag and also widens the utilization of silicon manganese slag.
