This work had as its objective to investigate the microstructural aspects of red ceramic incorporated with sludge from water treatment plant fired at 700°C. The sludge was collected at the filter stage in the water treatment plant of the county of Itaperuna, Rio de Janeiro State. The microstructure of the ceramics was analyzed with X-ray diffraction and scanning electron microscope with energy dispersive spectroscopy, EDS, facility. The results indicated that the incorporation of filter sludge change the fired phases and increases the microstructural defects of the ceramic.
