Abstract
This work aims at exploitation of the ceramic waste material for alumina extraction through mixing with KHSO4 as a fluxing agent. The chemical composition of the ceramic waste sample as well as the extracted alumina sample was investigated using X-ray fluorescence (XRF). The mineralogical composition and crystal size of the extracted alumina sample was investigated using X-ray diffraction (XRD). Transmission electron microscope (TEM) was used to study the grain size of the extracted alumina particles. Highly pure (99.37%) nano alumina particles (<50 nm) could be extracted from the ceramic waste sample. The efficiency of alumina extraction is 99.06%.
