It has been shown that the method of Keating & Warren [ Rev. Sci. Instrum . (1952), 23 , 519–522] for performing correction to the shapes of X‐ray profiles in order to allow for absorption broadening can lead to serious errors for materials with a low absorption coefficient. The factors influencing the degree of absorption broadening are reconsidered and the Keating & Warren analysis is re‐presented in the light of these considerations. The analysis is illustrated by correcting the 0004 X‐ray diffraction profile derived from a lightly pressed graphitized carbon.
