Zircon vanadium blue

Zirconium oxide is used in the production of ceramic colors or stains for ceramic tile and sanitary wares. Zirconia and siHca are fired together to form zircon in the presence of small amounts of other elements which are trapped in the zircon lattice to form colors such as tin—vanadium yellow, praseodymium—zircon yellow [68187-15-5] vanadium—zircon blue [12067-91 -3] iron—zircon pink [68412-79-3] indium—vanadium orange (105—108). 

Vanadium Yellow or Vanadium-Tin Yellow. A ceramic colour produced by the calcination, at about 1000°C, of a mixture of 10-20% V2O5 (as ammonium metavanadate) and 80-90% Sn02- A stronger yellow results if a small amount of Ti02 is added. These colours can be used in most glazes and either Sn02 or zircon can be used as opaciher. Vanadium-Zirconium Blue (or Turquoise). See zirconium-vanadium... 

Much of the information is covered in the patent literature. Zircon-vanadium blue was one of the most significant iimovations in color technology for several decades. Seabright was also responsible for the praseodyiruum yellow and the zircon-iron coral pink. 

Lattice type. The dopant ion replaces a Zr " ion in the zircon lattice, e.g., vanadium blue replaces ZF ) and praseodynuum yellow (Pt replaces Zt +). 

Lattice type. The dopant ion replaces a Zr ion in the zircon lattice, e.g., vanadium blue (V replaces Zr ) and praseodymium yellow replaces Zr ). Encapsulated type. Discrete particles of the colorant are trapped inside zircon crystals, e.g., the iron coral pink where very fine particles of red Fe203 are incorporated in zircon crystals. 

In 2003, Dajda et al. used multinuclear Si, and Zr SSNMR experiments to probe the vanadium distribution in vanadium-doped zircon [44], as previous studies had provided conflicting information on doping site preferences. Although it was understood that V ions were responsible for the blue color in V-doped zircon, the authors specifically sought to...
