      Gargori, Carina; Cerro Lloria, Sara; Galindo Llorach, Roberto; García López, Araceli; Llusar, Mario; Monrós, Guillermo Elsevier (2012-08)
      Solid solutions Ca(DxM1−x)O3 (M = Ti, Zr and D = Fe,Cr), have been studied as ceramic pigment in conventional ceramic glazes using 0.5 mol/mol of NH4Cl as flux agent by solid state reaction and by ammonia coprecipitation ...

    • openAccess   New chromium doped powellite (Cr–CaMoO4) yellow ceramic pigment 

      Galindo Llorach, Roberto; Gargori, Carina; Fas, Natalia; Llusar, Mario; Monrós, Guillermo Elsevier (2015-06)
      A new chromium doped powellite (Cr–CaMoO4) yellow ceramic pigment alternative to yellow of praseodymium-zircon has been synthesised and characterised in order to analyse: (a) the stoichiometry of the solid solution, (b) ...

    • openAccess   New chromium-calcium titanate red ceramic pigment 

      Gargori, Carina; Galindo Llorach, Roberto; Llusar, Mario; Cerro Lloria, Sara; García López, Araceli; Monrós, Guillermo Trans Tech Publications (2010)
      Synthesis and characterization of a new chromium- calcium titanate red ceramic pigment is described in this communication. The pigment is based on the solid solution of chromium (IV) in calcium titanate and was characterized ...

    • openAccess   Photoluminescence of synthetic titanite-group pigments: A rare quenching effect 

      Nasdala, Lutz; Lyubenova, Teodora; Gaft, Michael; Wildner, Manfred; Diegor, Wilfredo; Petautschniga, Christian; Talla, Dominik; Lenz, Christoph Elsevier (2014)
      Chromium-doped titanite and malayaite samples, which were synthesised to evaluate their performance as ceramic pigments, show remarkable photoluminescence behaviour. Emissions of centres related to traces of trivalent ...
