硅铁中硅含量的分析方法比较

Comparison of Measuring Methods for Silicon Content in Ferrosilicon

对半熔剂分解-聚乙二醇速凝聚硅胶重量法和氟硅酸钾容量法测定硅铁中的硅含量进行了比较。结果表明:重量法分析硅含量时间长、不稳定,难以满足大批量的样品的分析测定;氟硅酸钾容量法分析硅含量操作简便、快捷、准确,适合进行大批量的分析测定。

Comparison is made between semi flux decomposition- polyethylene glycol fast solidified silica gel gravimetric method and potassium fluosilicate volumetric method for measuring silicon content in ferrosilicon.Results show gravimetric method is difficult to catch up with big batch sample measurement due to long and unstable measurement while potassium fluosilicate volumetric method is suitable by its easy,fast and accurate measurement.
