摘要: Abstract The novel non-toxic yellow-orange inorganic pigments La2Ce2-xW0.5xFe0.5xO7+δ (x = 0.1, 0.3, 0.5, 0.7, 0.9) with high near-infrared reflectance have been synthesized. crystal structure, chemical composition, optical properties (reflectance and absorption properties) color performance of the synthesized were characterized by several techniques. X-ray diffraction analysis indicated disordered defect fluorite-type structure pigments. typical pigment La2Ce1.5W0.25Fe0.25O7+δ possessed NIR solar 82.05% orange (L* = 77.21, a* = 8.79, b* = 35.80). Also influence calcination temperature has studied, higher resulted in enhanced slightly reduced properties. applicability La2Ce1.7W0.15Fe0.15O7+δ (calcined at 1150 °C) was tested on a galvanized sheet, coating improved from 19.18% to 71.07%. acid/alkali resistance studies confirmed chemically stable. Thus, vivid exhibited application potentials.
