The effect of pH on partial size of ferrimagnetic powders prepared by auto combustion method

الملخص EN

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, particle size and density as a function of the (pH), and used Infrared spectroscopy (FTIR) to determine the internal structure of models, and also has been studying the microscopic structure took photos by electron scan microscopy (SEM) where indicated formation of high porosity homogeneous this change in the acidity coefficient(pH) led to change particle size and therefore a change in the properties of structural and physical .
