In this paper, we suggest an iterative correction method for indexing powder diffraction patterns when the rough unit-cell dimensions are known. When the error of the original rough unit cell dimensions is not very large (<1-3%) and the measurement data of diffraction line are precise (△2θ<0.04°), satisfactory results can be obtained.
