For this reason, V–ZrO2 and V–SnO2 yellow pigments, in which V2O5 is included or deposited on ZrO2(m)5 and SnO2
6 grains respectively, present reproducibility problems in industrial conditions. If novel yellow pigments are not obtained, the only yellow ceramic pigment in the future will be Pr– ZrSiO4. The research in the ceramic pigment field is
consequently focused on two possible alternatives: to obtain a new host structure or to improve the colours
already existing. The obtention of a yellow colour based on the solid solution mechanism will be an alternative to
Pr–ZrSiO4 in order to get more reproducible yellow colours.
