Abstract：
The effect of calcinate temperature on properties of ferric oxide dye,produced from iron mud through the dry process,was studied in this paper.The samples were investigated by XRD and chromatic analysis.The results showed that calcinate temperature was an important factor in the preparation process of iron oxide.When calcinate temperature below 700 ℃,the iron oxide crystal was not integrity and the color was light;while at 800 ℃,the crystal was α-Fe_2O_3;and while above 900 ℃,the crystal had no change but the color became dark.
