The Metal Organic Decomposition (MOD) route based on the chelation of a solution of metallic salts (usually nitrates) by
policarboxylic acid (oxalic and citric), applied to the synthesis of ceramic pigments based on chromium and vanadium doped
CaTiO3 perovskite, is presented in this paper. MOD synthesis allows preparing ceramic inks using the raw emulsioned
materials directly or the nanostructured charried powders at 500ºC dispersed in DEG, and also stable ceramic pigments in
glazes when the particle size and crystallization are sufficiently. In the CaTiO3 perovskite 20% molar modified with vanadium
in the Ti position, ceramic inks using charried powders produce adequate orange shades and the fired powders at 1000ºC
produce adequate orange colours in glazes. Samples of 1.5 molar addition of policarboxylic acids show the best pigmenting
properties. In the case of CaTiO3 perovskite 1% molar modified with chromium in the Ti position, ceramic inks using charried
powders produce adequate pink shades and the fired powders at 1000ºC produce adequate pink colours in glazes. Samples
of 0.25 molar addition of policarboxylic acids show the best pigmenting propertie
