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 . Se describe el óxido de vanadio-tantalio con manganeso que puede representarse por la fórmula MnxVyTazOw, donde 1 = x = 3, 0.001 = y = 3, 0.001 = z = 2, y w = 7, métodos de producción de MnxVyTazOw y una partícula que incluye MnxVyTazOw y una capa de vidrio de calcogenuro, y un método de producción de partícula. El óxido de de vanadio-tantalio con manganeso proporciona productos con una fase de pureza, apariencia y desempeño superior y toma en cuenta la salud y la seguridad. La construcción de la partícula descrita combina las propiedades de reflectividad del sustrato con las propiedades reflectivas casi infrarrojas de MnxVyTazOw mientras que la capa de vidrio de calcogenuro proporciona un aspecto estético. El método de producción de partícula descrito implica el depósito de vapor físico de MnxVyTazOw y/o la capa de vidrio de calcogenuro.
