摘　　要：以镍渣及粉煤灰为主要原料制备R2O-MgO-Al2O3-SiO2系微晶玻璃,通过加入不同种类及质量分数的碱金属氧化物,探讨碱金属氧化物对微晶玻璃理化性能的影响.结果表明:利用镍渣制备的微晶玻璃致密且性能良好;加入Li2O、Na2O使得微晶玻璃物理性能随碱金属氧化物质量分数的增大而提高,当Na2O质量分数为10%、Li2O质量分数为2%时,其抗折强度可达138.34 MPa.微晶玻璃耐酸性与耐碱性则随碱金属氧化物质量分数的增大而降低.The nickel slag and fly ash were used to prepare the glass-ceramic of R2O-MgO-Al2O3-SiO2 series.By adding different types of alkali metal oxides with different mass-fraction,the influence of alkali metal oxides on physical and chemical performance of glass-ceramic was discussed.The result showed that preparing the glass-ceramic with nickel slag,the glass-ceramic was compact and had good properties.The physical properties of the glass-ceramics with Li2O and Na2O increased with the content of alkali metal oxides.When mass-fraction was 10% Na2O and 2% Li2O,its flexural strength reached 138.34 MPa.Alkali resistance and acid resistance of glass-ceramics reduced with the mass-fraction of alkali metal oxide.
