2011 m. Nr. 1 SEM characterization of sol–gel–derived precursors,
novel black pigments and glazes
In the present work, the nanosized yttrium iron garnet (Y3Fe5O12), yttrium perovskite ferrite (YFeO3), cobalt, nickel and zinc iron spinel (CoFe2O4, NiFe2O4 and ZnFe2O4, respectively) powders were synthesized by an aqueous sol-gel process. These compounds have been used for the first time as precursors for the preparation of black ceramic pigments. The possible application of the obtained black ceramic pigments as ceramic glazes was also demonstrated. The microstructural evolution and morphological features of the obtained transition metal ferrites, pigments and glazes were studied by scanning electron microscopy (SEM). Keywords: transition metal ferrites, sol-gel process, black ceramic pigments, glazes, SEM |
