摘　　要：阐述了石墨电极抗氧化涂料中氧化锆分析方法,试样经硼砂—碳酸钠混合熔剂熔融,采用ICP-AES测定氧化锆。确定了仪器的最佳分析条件,选择锆的分析谱线为327.305 nm。该法已用于石墨电极抗氧化涂料中氧化锆的测定,测定结果与化学法相符,相对标准偏差(n=7)在1.0%以内,加标回收率在98%~100%。The analysis method of Zirconia is stated in antioxidant coatings of graphite electrode. The samples are melted by borax-sodium carbonate mixed flux,determining Zirconia content by ICP-AES. The analytical spectral line of 327. 305 nm is selected. The method has been applied to the determination of Zirconia in electrode antioxidant coatings,the results are consistent with the chemical method. The relative standard deviation（ n = 7） is less than 1% and the recovery rate is between 98% and 100%.
