硅铁中硅的测定,以往多用氟硅酸钾容量法,该法虽然速度较快,操作简便,但测定结果受温度的影响较大。据文献介绍,氟硅酸钡容量法可以消除温度对沉淀溶解度的影响,因而在南方炎热的天气里也能较稳定、准确地测定硅铁中的硅。 Ferrosilicon in the determination of silicon fluoride in the past with more capacity method, although the method of fast, easy to operate, but the measurement results by the temperature greater impact. According to the literature, the barium fluorosilicate volumetric method can eliminate the influence of temperature on the solubility of the precipitate, so that the silicon in the ferrosilicon can be more stably and accurately measured in the hot weather in the south.
