Synthesis of High-Purity Fe₂TiO₅ Powders Utilizing a Local Ironstone

Abstract:

The synthesis of Fe₂TiO₅ powders has been successfully performed by making use of Fe₂O₃ and TiO₂ powders. The Fe₂O₃ powder was obtained from local ironstone in Tanah Laut, South Kalimantan, while the TiO₂ powder was a commercial product. The Fe₂O₃ powder was obtained from the local ironstone through coprecipitation method on pH 5, followed by calcination at 800 °C for 1 hour. The synthesis of Fe₂TiO₅ powder was done by mixing the raw powders using Planetary Ball Mill method for 5 hours. Thermogravimetric dan Differential Thermal Analysis (TG-DTA) was performed to estimate the calcination temperature. The milled mixtures were then calcined at temperatures of 700 – 1100 °C. X-Ray Diffraction (XRD) data showed that Fe₂TiO₅ formation started at 800 °C with a weight fraction of 3.60 wt%. The XRD data also showed that at 1100 °C the Fe₂TiO₅ formation has completed. The crystallite size of Fe₂TiO₅ powders was 50 and 66 nm after calcination at 900 and 1100 °C, respectively.
