摘要：
Lathe waste contains high iron, therefore it has the potential to be a precursor in hematite (alpha-Fe2O3) synthesis. In this work, hematite was synthesized from lathe waste using the co-precipitation-calcination method with variation time of calcination: 1, 2, 3, 4 hours. The X-Ray diffraction data showed that the goethite (alpha-FeOOH) phase was obtained at precipitation stage then transformed to hematite (alpha-Fe2O3) phase after calcination and there is no impurities. The image of scanning electron microscopy showed that the distribution of particle size was not uniform. The color parameter showed that the highest chroma was achieved for 3 hours calcination.
