Effect of Sintering Temperature on Microstructure of Porous Materials Using Iron Tailing and Shale

Abstract:

Article Preview

A type of porous material was prepared mainly using iron tailings and shale, adding foaming agent, fusing agent and flexibility agent. To determine the sintering system of porous materials basing on iron tailing and shale, the effect of sintering temperature on the microstructure of the samples was investigated by XRD and SEM as well as section topography. The results indicate that both the porosity and pore size of the samples become higher and bigger respectively as sintering temperature increases from 1100°C to 1130°C, while mineral phase anorthite decreases; when sintered at 1120°C, the size of pores is approximately the same with the mean pore size of 1.5mm; the pores are larger and some get connected to the adjacent pores when the sintering temperature increases to 1130°C.
