  • MANGANESE VANADIUM TANTALUM OXIDE AND PIGMENTS HAVING A BLACK METALLIC EFFECT COATED WITH THE SAME
    Publication number: 20120016058
    Abstract: Manganese vanadium tantalum oxide that can be represented by the formula MnxVyTazOw, where 1?x?3, 0.001?y?3, 0.001?z?2, and w=7, and alternately, x=1.25?x?2.45, 0.1?y?2.39, 0.2?z?1.9, and w=7, methods of producing MnxVyTazOw, a pigment coated with MnxVyTazOw and a chalcogenide glass layer, and a method of producing the coated pigment are described. The disclosed manganese vanadium tantalum oxide has superior near-infrared reflective properties. The disclosed methods of producing the manganese vanadium tantalum oxide provide products with superior phase purity, appearance and performance and take health and safety into consideration. The construction of the disclosed coated pigment combines the reflective properties of the substrate with the near-infrared reflective properties of MnxVyTazOw, while the chalcogenide glass layer provides aesthetic appeal. The disclosed method of producing the coated pigment involves physical vapor deposition of MnxVyTazOw, and the chalcogenide glass layer.
