AB - Muscovite from a Brazilian natural source was beneficiated using knife mills and an ultrasound treatment. It was possible to achieve mica with a particle size of below 100 and above 45 μm and a thickness of between 0.5 and 1 μm. This product could be used for the synthesis of intensely coloured pearlescent pigments based on muscovite covered with rare earth oxides (CeO2, PrO2 and Ce0.95Pr0.05O2). Pigments were prepared by hydrolysis and characterised by X‐ray diffraction, thermal analyses (thermogravimetric/differential thermal) and scanning electron microscopy (MeV). The colour of the resulting pigments was analysed using the CIELab method, including a pearlescence index, and it showed the following colours: mica‐CeO2, yellow; mica‐PrO2, black; mica‐Ce0.95Pr0.05O2, orange.
