采用XRD 和 SEM 分析钛精矿热处理前后的相变过程， XRD 分析结果表明，钛精矿中主要是一些如 FeTiO3、Fe1.1 Ti0.9 O3、 Fe1.04 Ti0.96 O3、 Fe+2TiO3等复杂的固溶体，在800℃煅烧3 h时出现新相Mg0.208 Fe0.955 Ti0.833 O3。在1000℃煅烧3 h此时相对结晶度也发生了明显变化； SEM扫描电镜结果表明，在800℃煅烧3 h条件下颗粒疏松度提高，表面出现较多裂纹。

The phases of ilmenite were by analyzed XRD and SEM. XRD results showed that the main phases of original ilmenite were some complex solid solutions, such as FeTiO3、 Fe1.1 Ti0.9 O3、 Fe1.04 Ti0.96 O3、 Fe+2TiO3 , After heat treatment for 3 h at 800 ℃, Mg0.208 Fe0.955 Ti0.833 O3 was found. Crystallinity had also undergone tremendous changes at 1000 ℃ for 3 h. SEM results showed that the ilmenite particles were more lax and more surface cracks at 800 ℃ for 3 h.
