Abstract
The present work describes the characterisation of the two different polishing waste samples. The samples were analysed with laser particle size analyser, XRD, XRF, TGA, and SEM. In the sample A, a large amount of calcite (CaCO3) together with silica and aluminosilicates were observed with SEM. In the minerology, only CaCO3, CeO2 and LnO0.65F1.7 were found. In the sample B, very small amounts of impurities (<2%) were found. The particle size of sample B was decreased compared to it’s original polishing powder. CeO2 and LnO0.65F1.7 compounds were found in the XRD analysis.
