Effects of magnesium and cooling rate on titanium phase transformation for production of TiO2

Keywords： anosovite , karrooite , rutile , crystal structure , stability

以三种钛渣为研究对象，采用X射线衍射和晶体结构分析，研究镁含量和冷却速度对钛渣中钛物相转变的影响。结果表明，急速冷却的钛渣中，生成的钛物相为黑钛石，化学式为 MgnTi3?nO5(0

X-ray diffraction (XRD) and crystal structure analysis were used to study the effects of Mg content and cooling rate on the titanium phase transformation of three types of titanium slag. The results indicate that in the rapid cooling process, the titanium phase is anosovite, whose chemical formula is MgnTi3?nO5 (0
