The study investigates the use of cobalt and alkaline ions to produce stable purple and pink pigments with enhanced reflective properties, addressing the environmental and economic dimensions of pigment synthesis. The synthetic methodology integrates starch as an organic fuel in a green combustion strategy, offering environmentally friendly and cost-effective pigment production. Characterization techniques have been used to assess the properties of the synthesized pigments, including X-ray diffraction, field emission scanning electron microscopy, X-ray photoelectron spectroscopy, and Fourier transform infrared spectroscopy. The CoxMg1-xPO4 and LiCoxMg1-xPO4 pigments showed discernible improvements in NIR reflectance among the synthesized samples, achieving solar reflectance values (R%) of 75% and 70%, respectively. These findings emphasize the importance of composition in determining pigments' reflective properties, which are essential for their use in practical applications requiring thermal insulation and color aesthetics.Elsevier20262026-08-04 12:23:25Neznano31506UDK: 620.1/.2ISSN pri članku: 1879-3312COBISS_ID: 284039939Nizozemskasl© 2026 The Authors.
