摘要

A kind of far infrared radiation ceramics was prepared by using iron ore tailings, CaCO_3 and SiO_2 as main raw materials, and Ce as additive. The result of Fourier transform infrared spectroscopy showed that the sample exhibits excellent radiation value of 0.914 when doping 7 wt.% Ce. Ce~(4+) dissolved into iron diopside and formed interstitial solid solution with it sintered at 1150℃. The oxidation of Fe~(2+) to Fe~(3+) caused by Ce~(4+) led to a decrease of crystallite sizes and enhancement of Mg-O and Fe-O vibration in iron diopside, which consequently improved the far infrared radiation properties of iron ore tailings ceramics.
