Abstract A new equation for predicting the generated bremsstrahlung background intensity in electron‐probe x‐ray microanalysis has been verified experimentally. This equation is applicable to all bulk composite specimens and reduces to Kramers' equation for pure elements only. The experimental verification has been carried out for Al 2 O 3 , Fe 2 O 3 and ZrO 2 with radiation energies from 4.2 to 14.8 keV. The predicted bremsstrahlung intensities are in good agreement with the experimental data.
