The optimum conditions for determining carbon contents in various carbides were investigated by using an electron probe microanalyzer. Though the profiles of Cr Kα and Ni Lα lines overlapped partly with C Kα, the interferences could be eliminated by the use of a pulse height analyzer. The chemical shifts of C Kα lines were measured for several carbides. The accelerating voltages which give the maximum X-ray intensities of C Kα lines were 15, 10, 9.5, 9, 5.2, 2.7 and 2.5 for graphite, diamond, TiC, VC, Cr3C2, Mo2C, TaC, and WC, respectively. The X-ray intensities of these carbides were almost proportional to the carbon contents. The absorption corrections for SiC and B4C were calculated by Philibert's and modified Philibert's equations. The applicability of those equations was discussed.
