Enhancing Heat Resistance of Red Color by Coating Fe2O3 Nanoparticles with Mesostructured Silica
The surface of α-Fe2O3 nanoparticles was successfully coated with mesostructured silica templated by surfactant assemblies using cetyltrimethylammonium ions. By repeating the coating operation, it was possible to control the thickness of the mesostructured silica phase. In the sample obtained with ten coatings, in particular, the aggregation and sintering of the α-Fe2O3 nanoparticles was suppressed, and the bright red before the heat treatment was maintained even after a heat treatment at 1300 °C.
