Monoferrite BaFe2O4 applied as ceramic pigment
Source abstract
Abstract
Abstract This work had the objective of studying the ceramic pigment BaFe 2 O 4 , which presents iron as the chromophore ion, and barium as net modifier. Synthesis was done by the polymeric precursor method. After calcination at different temperatures, characterizations were done by X-ray diffraction, infrared spectroscopy, surface area by BET, scanning electron microscopy, UV–vis spectroscopy and colorimetric analysis, using CIELab system. The soft chemical synthesis method leads to a high crystallinity material after calcination at 700 °C, while usual methods require higher temperatures (above 850 °C) or lead to secondary phases. The powders were applied on ceramic pieces in order to evaluate the behavior of the system when added to a glaze. Pigments presented dark brown color, with homogeneous surfaces of the glaze.
