摘要:
以铝土矿尾矿和钒钛磁铁矿尾矿为原料，经混料、成型和高温烧成等工艺制备了刚玉质复相陶瓷，研究了钒钛磁铁矿尾矿添加量、烧成温度等因素对制得复相陶瓷材料的物相、显微形貌及力学性能的影响规律。结果表明：当铝土矿尾矿与钒钛磁铁矿尾矿质量比为9∶1时，在1100 ℃下保温3 h制得刚玉质复相陶瓷材料的性能最优，其体积密度为2.71 g/cm3，抗压强度为276.9 MPa，抗折强度为67.3 MPa。
Abstract:The corundum based composite ceramics were prepared via a high temperature sintering process, using the bauxite tailings and vanadium−titanium magnetite tailings as raw materials. The effects of vanadium−titanium magnetite tailings addition and sintering temperature on the phase composition, morphology, and mechanical properties of the as−prepared composite ceramics were investigated in detail. The results indicated that the best performances were observed with the content ratio of 9∶1 between bauxite tailings and vanadium−titanium magnetite, after sintering at 1 100 ℃ for 3 h. The optimized volume density, compressive strength, and flexural strength were 2.71 g/cm3, 276.9 MPa, and 67.3 MPa, respectively.
