摘　　要：X射线衍射法代替化学法测定烧结矿中两价铁含量是X射线衍射定量相分析应用的重大成果,它不仅分析速度快、数据重现性好、操作简便,最重要的是分析结果可信度高,它直接显示了烧结矿中与两价铁有关各物相含量的变化,可直接用于控制烧结工艺的在线分析。 用X射线衍射法测定烧结矿中两价铁含量必须满足下述三项重要条件:(1)测量出与两价铁有关的全部物相X射线衍射强度;(2)测量上述各物相衍射强度时,必须扣除其他物相干扰峰的强度,测得的强度值应符合强度公式;(3)烧结矿的原料不同或配比变化时,要及时测量X射线衍射全谱图(d=5.0-1.O),进行物相鉴定,必要时应对原分析程序作适当修改。 采用X射线衍射仪可以满足上述条件的要求,而衍射扫描道法则不能。Using XRD quantitative method instead of wet chemical in ditenninadon of ferrous compound concentration is of great significance, XRD method not only rapid presise, simple but also the result is more reliable, it displays directly the different phases of ferrous compounds in sinter ore, and will be directly used in control of sinter process.Using XRD method the following three conditions must be fulfilled:(l) Measurement of all ferrous compound phases diffraction intensity. (2) Correction of interference peak must be done in different ferrous phases intensity. (3) When the raw materials ore receipe was changed, the whole diffraction spectrum ( d = 5.0 ~ 1 .0A), indentiflcation of phases must be remeasured to modify original program.All above conditions the diffraction scanning channel method is not possible fulfilled.
