Abstract

Lathe waste from iron craft industry encompassed high iron that potential to be ferric precursor to synthesize maghemite pigment. In this research work, maghemite pigment was synthesized by the precipitation-calcination method using the variation of temperature: 300, 350, 400 and 450oC. The XRD data indicated the formation of magnetite at precipitation stage and then transformed into maghemite after calcination. X-ray diffraction data showed that maghemite has a tetragonal structure with space group P43212. The result showed that the particle size of maghemite increase with increasing temperature. Based on the color parameter, maghemite synthesized at 350oC has the highest lightness. From the SEM-EDS data shows that maghemite has the distribution of particle size was not a uniform and still have impurities, such as carbon and Manganese.
