Title: High-performance yellow ceramic pigments Zr(Ti{sub 1-x-y}Sn {sub x-y}V {sub y}M {sub y})O{sub 4} (M = Al, In, Y): Crystal structure, colouring mechanism and technological properties

Abstract

Zirconium titanate-stannate doped with V with co-dopants Al, In or Y was synthesised by solid state reaction and its structural (XRD, SEM), optical (DRS) and technological properties were determined to assess its potential use as ceramic pigment. These compounds have a srilankite-type, disordered orthorhombic structure, implying a random distribution of Zr, Ti, Sn and dopants in a single, strongly distorted octahedral site. Doping caused an increase of unit-cell dimensions, metal-oxygen distances and octahedron distortion. Optical spectra show crystal field electronic transitions of V{sup 4+} as well as intense bands in the blue-UV range due to V{sup 4+}-V{sup 5+} intervalence charge transfer and/or to V-O charge transfer. The formation of oxygen vacancies is supposed to compensate the occurrence of V{sup 4+} ensuring the lattice charge neutrality. These srilankite-type oxides develop a deep and brilliant yellow shade with colourimetric parameters close to those of industrial ceramic pigments. Technological tests in several ceramic applications proved that zirconium titanate-stannate is very stable at high temperature, exhibiting an excellent performance in the 1200-1250 deg. C range, even better than praseodymium-doped zircon.
