高炉渣中非晶态物质含量的定量分析

Quantitative Analysis on Amorphous Phase Content in Blast Furnace Slag

首先通过化学分析法和X射线衍射法,准确确定高炉渣中的物相组分,然后通过加入标准物质CaF_2,对高炉渣的物相组分进行定量分析,并使用K值法计算出非晶态物质的含量。结果表明:采用X射线衍射法和K值法相结合的方法可以快速准确地测得高炉渣中非晶态物质含量;且标准物质CaF_2的加入质量分数控制在20%时,测定结果更加准确。

Firstly the phases in blast furnace slag were determined by chemical analysis and X-ray diffraction analysis.And then the content of each phase was quantitatively analyzed by adding standard materials CaF2 and the amorphous content was also calculated by K-value method.The results indicate that the amorphous phase content in blast furnace slag can be quickly and accurately determined by combining X-ray diffraction method and K-value method,and when the standard materials CaF2 addition amount is 20%,more accurate results can be obtained.
