摘要
本文采用碱溶 ICP- AES法对 Al Si/Si C复合材料中的高含量硅和低含量镁、钛、铁的测定进行研究 ,着重进行基体元素铝及待测定元素硅、镁、钛、铁之间的干扰试验 ,进行了碱度试验和酸度试验 ,测定了Al Si/Si C复合材料中的硅、镁、钛、铁含量 ,得到了较好的精密度和准确度。方法简便可靠 ,可获得满意的分析结果。
It is described in this paper that the sample is dissolved in NaOH and high concentration Si and low concentration Mg, Fe, Ti in AlSi/SiC composite material can be determined by ICPAES and the effects of matrix and coexist elements in AlSi/SiC composite materials on Si, Mg, Fe, Ti are emphatically studied. The effects of HCl and NaOH on the determined element are also studied. High precision and accuracy are obtained.
