Red and red-shade violet inorganic oxide materials containing cobalt

摘要

The current technology is directed to red and red-shade violet pigments with an hexagonal ABO₃ structure of the form Y(In, M)O₃ in which M is substituted for In in the trigonal bipyramidal B site of the ABO₃ structure, and where M is a mixture containing Co²⁺ and charge compensating ions, or M is a mixture containing Co²⁺ and charge compensating ions, as well as other aliovalent and isovalent ions.
