“…The impressive optical (e.g., CoAl 2 O 4 is well known as Thenard's Blue) and chemical (catalytic applications) properties of transition-metal aluminates make them of significant interest as nano-pigment and catalysts [1,2]. For example spinel AMn 2 O 4 (A = Cu, Zn) [3] has been performed well for photocatalyzing water splitting into H 2 and O 2 .…”

Nanocrystalline Copper aluminate (CuAl 2 O 4 ) was prepared by sol-gel technique using aluminum nitrate, copper nitrate, diethylene glycol monoethyl ether and citric acid were used as precursor materials. This method starts from of the precursor complex, and involves formation of homogeneous solid intermediates, reducing atomic diffusion processes during thermal treatment. The formation of pure crystallized CuAl 2 O 4 nanocrystals occurred when the precursor was heat-treated at 600°C in air for 2 h. The stages of the formation of CuAl 2 O 4 , as well as the characterization of the resulting compounds were done using thermo-gravimetric analysis, X-ray diffraction, scanning electron microscopy and Fourier transform infrared spectroscopy. The products were analyzed by transmission electron microscopy and ultraviolet-visible (UV-Vis) spectroscopy to be round, about 17-26 nm in size and E g = 2.10 eV.

“…A few available studies focus on the interaction between pigments and different types of glazes (chrome-tin pink sphene [8][9][10], brown Cr-Fe-Zn-Al spinel [11], and also the chromium-iron black [12]). More recently, inkjet technology has promoted the study of interactions between glazes and nanosized pigments [13]. However, pigment interactions with other types of ceramic products have not been addressed.…”

“…The use of pigmenting particles at the nanoscale is necessary for inkjet applications [12,13]. At present in the industry, these nanoparticles are basically obtaining by different milling steps [14,15]. The use of nanopigments in inkjet technology can solved problems like nozzle clogging, dispersion or instability caused by micronized pigments, and moreover, remove the milling stages [16].…”

Nanoparticles of the ceramic pigment with composition Ti 0.97 Cr 0.015 Sb 0.015 O 2 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.
