Propiedades ópticas del pigmento α-Fe<sub>2</sub>O<sub>3</sub>/SiO<sub>2</sub>

Propiedades ópticas del pigmento α-Fe<sub>2</sub>O<sub>3</sub>/SiO<sub>2</sub>

Presently work describes the synthesis of the pigment α-hematites/SiO2 according to the method of mixture of oxides. The red color of the pigment corresponds to the transitions electronic 6A1g→4T1g y 6A1g→4T2g of the ion Fe+3 that presents the configuration structural d5 and it is connected to six o...
