Chemical methods to synthesize FeTiO<inf>3</inf> powders

Abstract:

Three different techniques were used to synthesize FeTiO3 powders. The first method is simple coprecipitation of both Fe and Ti ions under basic conditions using standard ammonia solution from aqueous ferric nitrate and titanium oxy chloride. This precipitate on heating at 400 °C produces ilmenite phase. The second method is to digest hydroxide precipitates at 100 °C to form FeTiO3 phase. The third technique is to make use of citrate process to form FeTiO3 powders. The phase contents and lattice parameters were studied by powder X-ray diffraction (XRD). Particle size and morphology were studied by Transmission Electron Microscopy (TEM). © 2005 Elsevier B.V. All rights reserved.
