Abstract

Ferrite materials, especially those containing nickel and cobalt, are popular due to their unique mechanical and magnetic properties. Single phase NiFe2O4 and CoFe2O4 nanopowders obtained by different methods were used for sintering studies. Chemical sol-gel self-propagating combustion method, co-precipitation technology combined with hydrothermal synthesis or spraydrying method, and high frequency plasma chemical synthesis have been used to synthesize ferrite nanopowders. Relatively dense (95-99%) materials with high saturation magnetization (MS = 80-84 emu/g for CoFe2O4 and MS = 46-48 emu/g for NiFe2O4) were obtained at 1100-1200 °C temperatures.
