This paper deals with the possibility to synthesise the SnO2/Cr cassiterite violet pigments
in which a part of stannic ions has been substituted by the transition-metal or rare-earth
metal ions, respectively. Pigments with a general formula of Sn0.99Cr0.005M0.005O2 or
Sn0.99Cr0.005Ln0.005O2 (where M = Ti, Zr and Ln = Tb, Ce) have been prepared by the
solid state reactions at high calcination temperatures; namely, in a range from 1350 to
1500 °C. The aim was to develop the conditions for such a synthesis of this type of
pigments and to determine the effect of admixed species on the colour properties of these
compounds. Synthesised pigments were characterised in terms of colour properties after
their application into ceramic glaze and organic binder. The compounds of interest have
also been studied with respect to their phase composition, as well as the particle size
distribution, finding that they may represent a potential extension of the range of violet
shades applicable in practice; especially, when speaking about their use in ceramic
industry.
