During the preparation of this research ferrites-copper powder chemical auto-combustion method ,has been studying the effect of changing of (pH=3, 5, 7, 9, 11) coefficient on the particle size of the powder, used Debye-Scherrer Formula, to calculate the particle size by use of the highest peak (311) in X-ray diffraction (XRD) were obtained particle size ranges (11.5-13.75) nm, and also has been compared to the values obtained in drawing curves that represent change the lattice constant,
