Calcium doped nickel ferrite powders have been prepared by sol-gel combustion technique. Metal nitrates, such as calcium nitrate, nickel nitrate and ferric nitrate, were used as the source materials and citric acid and polyvinyl alcohol were used as the burning agent and agglomeration reducing agent, respectively. The average crystallite size of the prepared ferrite was in the order of ~70- 92 ...

Abstract The current work involves the use of flash auto combustion procedure to synthesize nano-ferrites Mn 0.6 Zn 0.4 La x Fe 2-x O 4 , ( = 0.00, 0.02, 0.04, 0.06, 0.08, and 0.10) annealing at 500 °C for h. X-ray Diffraction (XRD), Fourier transition infrared spectroscopy (FTIR), high-resolution transmission electron microscopy (HRTEM) were used characterize structural properties produced sam...

Abstract M–Co $${\mathrm{Fe}}_{2}{\mathrm{O}}_{4}$$ Fe 2 O 4 (where M=Cu and Zn) nanoferrites were successfully prepared using the citrate auto-combustion technique. The main idea was drawn through a complete stud...
