| description | Alumina and zirconia thin films modified with colored nano-Fe<sub>x</sub>O<sub>y</sub> pigments were sintered by the flash-lamp-annealing method. We selected a nano α-Al<sub>2</sub>O<sub>3</sub> and micron α-Al<sub>2</sub>O<sub>3</sub> bimodal mixture as the base precursor material, and we doped it with 5 vol% of Fe<sub>x</sub>O<sub>y</sub> red/brown/black/yellow pigments. The coatings were deposited from nanoparticle dispersions both on glass and on flexible metal foil. The characteristics of the thin films obtained with the use of various additives were compared, including the surface morphologies, optical properties, crystallinities, and structures. Flash lamp annealing was applied with the maximum total energy density of 130 J/cm<sup>2</sup> and an overall annealing time of 7 s. Based on the simulated temperature profiles and electron-microscopy results, a maximum annealing temperature of 1850 °C was reached for the red Al<sub>2</sub>O<sub>3</sub>: Fe<sub>2</sub>O<sub>3</sub> ceramic film. The results show that red α-Fe<sub>2</sub>O<sub>3</sub> pigments allow for the achievement of maximum layer absorption, which is effective for flash lamp sintering. It was also possible to use the selected red α-Fe<sub>2</sub>O<sub>3</sub> particles for the flash-lamp-assisted sintering of ZrO<sub>2</sub> on a 30 µm-thin flexible stainless-steel substrate. |
