Recent advances in low-cobalt substrate-based cobalt blue composite pigments: Structural engineering, sustainable synthesis, and multifunctional applications

Cobalt blue (CoAl 2 O 4 ) is a spinel-structured inorganic pigment characterized by high chemical and thermal stability. However, its broader industrial application is constrained primarily by the high cost and supply volatility of cobalt and by the energy demand of conventional...
