Highly Dispersed Re-Doped CoAl2O4 Nanopigments: Synthesis and Chromatic Properties

Highly Dispersed Re-Doped CoAl2O4 Nanopigments: Synthesis and Chromatic Properties

Nanosized spinel CoAl2-xRexO4 complex oxides were prepared by self-propagation combustion method. The products have been characterized by XRD, SEM, and EDS. The results indicated that Al3+ can be partly replaced by Re3+ when the doped amount is less than 10%, which forms single solid solution. The N...

The products have been characterized by XRD, SEM, and EDS. The results indicated that Al3+ can be partly replaced by Re3+ when the doped amount is less than 10%, which forms single solid solution. The NIR reflectance and chromatic properties of samples have also been investigated. The substitution of Re3+ for Al3+ in CoAl2O4 can increase the blueness of pigments. SEM results revealed that the obtained CoAl2-xRexO4 pigments consisted of highly dispersed spherical-like nanoparticles with uniform size distribution. EDS results indicated that the distribution of element was considerably uniform with no chemical segregation phenomenon.http://dx.doi.org/10.1155/2016/4169673
