Nanoparticles of the ceramic pigment with composition Ti0.97Cr0.015Sb0.015O2 were
prepared by microemulsion-mediated solvothermal method at 180 ºC. Anatase or rutile
single phase was obtained depending on the synthesis conditions. Scanning electron
microscope analysis showed the formation of nanospheres with particle size around 600
nm. The anatase to rutile transformation temperature was determined by Raman
spectroscopy. The evolution of the colour was studied, and it was related with the
polymorphic transition. Yellow nanopigments were obtained at low temperature and
huge orange colour was observed at high temperature. Nanopigments prepared at 180
ºC were tested with an industrial frit. Similar chromatic coordinates of an industrial
orange ceramic pigment obtained at high temperatures were observed. -potential
values of the nanoparticles were -57 mV. The size, shape, colour and electrostatic
stability of these nanoparticles make them potential candidates to be applied in glazes or inkjet printers as orange ceramic pigments. [-]
