摘要：

Glow discharge atomic emission spectrometry (GD-AES) and the classical spectrometric method with a d.c. arc source (D.c.-arc-AES) were applied to the direct solid sample analysis of SiC powders. The homogenity of pellets prepared from mixtures of SiC with copper powder and used for the GD experiments was investigated in detail. Various methods were tested for the analytical calibration and applied to the direct analysis of technical SiC powders. The experimental data were evaluated by using chemometric procedures. The results of the two methods were compared.
