This paper presents the evaluation of battery waste as a potential pigment for ceramic materials. The battery waste used comes from the primary batteries, zinc-carbon and alkaline batteries. Battery waste powder characterized alone and mixed with TiO2 as reference color value. The thermal stability was studied with Thermo Gravimetric Analysis (TGA). Electron Microscopy (SEM) and X-ray diffraction (XRD) were used to investigate the powder morphology, as well as the microstructure evolution. Measurements of color coordinates L*a*b* were conducted using a spectrophotometer. The ceramic pigments prepared were subjected to different tests in order to evaluate its ceramic performance. Results showed that overall cobalt blue was the most stable component under high temperature and acidic environments.
