Preparation of Corundum Based Composite Ceramics Using Bauxite Tailings and Vanadium-titanium Magnetite Tailings as Raw Materials
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.
