摘　　要：文章主要对硅基复合材料中镁含量的检测方法进行了研究,其检测目的是准确地检测出在制备硅基复合材料过程中镁的含量,从而对最终产物中的硅酸镁含量进行控制。在实验过程中建立了用电感耦合等离子体发射光谱法(ICP-AES)测定硅酸镁-碳包覆氧化亚硅复合材料中镁含量的方法,最终验证其检出限为0.004 mg/L,检测结果的相对标准偏差均小于5%,线性相关系数达到0.999以上,该方法满足镁含量的测定。In the paper,the detection method of magnesium content in silica-based composite material is studied and its purpose is to accurately detect magnesium content in the process of preparing silica-based composite materials so as to control the content of magnesium silicate in final product.During the experiment,the method for determining magnesium content in magnesium silicate-carbon-encapsulated silicon oxide composite material with the inductively coupled plasma atomic emission spectrometry(ICP-AES)is established.Finally,it is verified that the detection limit is 0.004 mg/L,relative standard deviation of detection results is less than 5%and linearly dependent coefficient is above 0.999 so that this method is satisfied with the test of magnesium content.
