| 摘 要： | SiO2的测定是硅酸盐矿石、耐火材料、铁矿石、水泥分析中常规的分析项目。K2SiFs容量法置到．广量的应用，在国家标准GB／T176—1996被列入代用法。但是该法由于采用熔融分解试样，试样的处理比较复杂，且K2SiF6的溶解度受温度的影响较大。氟硅酸钡容量法测定SiO2较好地克服了上述缺点。

| Abstract: | SiO2 mensuration is a conventional analysis project to analyse silicate Ore, fire-resistant material, iron ore and cement. K2SiF6 volumetric analysis is widely applied. It is included in the substituting usage at the national standards GB/T176 - 1996. As it is adapted to meltdown the sample, the sample is very complex to deal with and the temperature has great influence upon solubihty of K2SiF6. The shortcomings of SiO2 mensuration are overcame by barium fluosilicate volumetric analysis. |
