摘　　要：以陕西某钼尾矿为主要原料,低品位金红石精矿为成核剂,采用烧结法制备钙长石和透辉石相微晶玻璃。探讨低品位金红石精矿加入量对钼尾矿微晶玻璃机械性能和化学稳定性的影响。结果表明,低品位金红石精矿的最佳添加量为8%,此条件下所得微晶玻璃的抗压强度、抗折强度分别为162.3 MPa、86.1 MPa,体积密度为2.93 g/cm^(3),耐酸、耐碱质量损失率分别为0.19%、0.16%。研究成果可为钼尾矿及低品位金红石精矿资源的高效利用提供新思路、新方法。Using molybdenum tailings from Shaanxi as the main raw material and low grade rutile concentrate as the nucleating agent,glass ceramics with anorthite as the main crystal phase and diopside as the secondary crystal phase were prepared by sintering method.The effect of low grade rutile concentrate on mechanical properties and chemical stability of glass ceramics with molybdenum tailing was investigated.The results show that the optimum addition of low grade rutile concentrate is 8%.Under this condition,the compressive strength and flexural strength of glass ceramics are respectively 162.3 MPa and 86.1 MPa,the volume density is 2.93 g·cm^(-3),and the mass loss rate of acid resistance and alkali resistance are 0.19%and 0.16%,respectively.The research results can provide a new idea and method for efficient utilization of molybdenum tailings and low grade rutile concentrate resources.
