“…Well-defined diffraction peaks start to appear at 600 • C and crystallisation proceeds in the cubic structure -with progressively better definition and sharpening of the peaks -up to 800 • C. No appreciable structural differences were found between the power electrodeposited in the absence and in the presence of chitosan. This result is coherent with literature reports regarding yttria electrodeposited from aqueous chloride and nitrate solutions [26,29] as well as from hydroalcoholic nitrate solutions [30].…”

“…The area ratio of Y 3d 5/2 to Y 3d 3/2 is close to the theoretical ratio of 1.5 and the binding energies of Y 3d 3/2 (159.7 eV) and Y 3d 5/2 (157.6 eV) are in agreement with the binding energies found in the case of an Y-OH binding. These results confirm that the electrodeposited film is an hydroxide as it was analysed by XRD [18].…”

Surface analysis performed on Ni20Cr coated by yttrium hydroxynitrate hydrate (jjj ¼0.2 mA · cm -2 , t = 300 s), after drying in air and before heat treatment: SIMS depth profiles (left) and XPS spectra (right) and confirm the transformation of the hydroxide into cubic yttrium oxide previously observed after heat treatment [18]. In addition, Cr 2p 3/2 peak is detected after heat treatment, whereas it was missing before heat treatment.…”

In order to introduce a so-called reactive element simultaneously at all the surfaces of a NiCr (Ni-20wt.%Cr-1.5wt.%Si) metallic substrate alloy, an easy to apply surface treatment was used: an yttrium containing thin film (constituted of a hydrated yttrium hydroxide nitrate) was electrodeposited from a mixed water-ethanol solution. After a thermal conversion treatment at 600 C under argon, leading to an Y 2 O 3 coating, specimens were submitted to high-temperature oxidation testing, under artificial air at atmospheric pressure, in order to evaluate in these conditions the effect of the coatings on the behaviour of the studied alloy. Expected effects of the introduced reactive element (REE) were effectively shown: decrease of the coated sample weight gain, suppression of the formation of the base metal oxides and change of the oxide grains morphology.

“…Y 2 O 3 can be used as highefficient additives and functional composite materials like yttria stabilized zirconia films [1][2][3][4]. This material could be synthesized via several methods, including cathodic electrodeposition [5][6][7][8][9], gas-phase condensation [10], precipitation [11], sol-gel [12], pyrolysis [13], solvothermal [14], and hydrothermal synthesis [15][16][17]. Among these methods, the easy and clean cathodic electrodeposition method has been proven to be a versatile and controllable technique for the preparation of nanostructured materials.…”

An easy two-step synthetic route is reported for the manufacture of yttrium oxide nanoparticles utilizing aqueous yttrium nitrate solution. In the first step, yttrium hydroxide precursor was grown on stainless steel electrode using a simple cathodic electrodeposition at room temperature. The subsequent second step includes the thermal decomposition of yttrium hydroxide powder at different temperatures for two hours. The synthesized products were characterized by means of X-ray diffraction (XRD), scanning electron microscopy (SEM), differential scanning calorimetery (DSC), FT-IR and Raman spectroscopy. Results showed that the as-deposited Y(OH) 3 is composed of nanoparticles with grain size of approximately 40-50 nm. Cubic-structured Y 2 O 3 phase with a porous morphology was finally formed when temperature was raised to 600• C. Results suggested that the final oxide nanoparticles are crystalline and consist only of yttrium oxide phase forming agglomerates of many primary particles with average diameter around 30 nm.
