Influ ene of pH on Structural Pro perties of Mn Ferri te Nanopa rticles via Sol - Gel Combustion Method

Manganese Ferrite belongs t o a group of soft ferrite materials r ecognized by high ma gnetic permeability. Nan oparticles of Mn Ferrite have widespread ap plications s uch as ma gnetic recording media, drug del ivery technology, ma gnetic resonance imag ing (MRI) [۱]. Prepa ration condition affected by sever al parameters such as pH of prec ursor, calcin ation temperature, calcinations tim e, rate of citrate to nitrate and atmosphere of the process. In this paper, effects of pH of the so lution on th e formation of manganese ferrite fin e particles by sol - gel combustion method, were investigated. The obta ined powder was characterized by XRD, TG - DTA, FT - I R and SEM analysis.
