Phase Formation, Structural, and Microstructural Characterizations of Ilmenite FeTiO₃ Nanopowder Prepared from Liquid-Mixing Method

Abstract Ilmenite FeTiO 3 is a wide-band gap antiferromagnetic semiconductor material and has very potential for applications in spintronic devices. Miniaturization of microelectronics communication systems become necessity. Thus that can achieve high properties small volume therefore favourite. For reason, particles the materials must also be nanoscale. This paper reports synthesis nano-sized powder using liquid-mixing method. Using this method, crystalline phase was initially formed at temperature as low 340 °C. The formation analyzed from room to 600 °C based on TGA/DTA, FTIR XRD data. Rietveld's analysis stated 84 % molar °C, rest TiO 2 rutile. By Scherrer average crystallite size calculated 38-43 nm, while TEM data provides grain sizes 20-40 nm.
