Formation of yttrium oxide by electrodeposition in organic electrolyte

Electrochemical deposition of yttrium oxide

“…16±18 Matsuda et al investigated electrodeposition of Y 2 O 3 in a dimethylformamide solvent containing a small amount of water. 16 However, for applications, requiring electrodeposition from aqueous solutions, it is important to clarify the effect of additives and processing parameters on deposit yield, deposit crystallinity and ®lm morphology. This research, motivated by the importance of yttrium oxide for various applications, also addresses the possibility of electrodeposition of organoceramic materials based on yttrium hydroxide.…”

Electrosynthesis of organic–inorganic nanocomposites

“…Cathodic electrosynthesis has been utilized for the fabrication of thin films and powders of individual oxides, complex oxide compounds and alloys [4][5][6][7][8]. Recently the possibility of cathodic electrosynthesis of composite materials containing inorganic nanoparticles and polymers has been demonstrated [8,9].…”

Synthesis of Y[sub 2]O[sub 3] Nanospheres via Heat-Treatment of Cathodically Grown Y(OH)[sub 3] in Chloride Medium

“…It is widely used as a high performance ceramic in nuclear and high temperature applications such as in oxide dispersion strengthened steels 1-3 and yttria-stabilized zirconia thin films. The formation of Y 2 O 3 by electrodeposition in organic electrolytes containing YCl 3 and a small amount of water was investigated by Matsuda et al 18 Tak and Lee synthesized Y 2 O 3 films on indium tin oxide by cathodic electrodeposition of yttrium hydroxide followed by heat-treatment. [14][15][16][17] Compared to other methods used for the production of nanostructures of yttrium oxide, the electrodeposition of such functional materials appears to be simple and highly sensitive.…”

“…However, despite the importance of electrochemical synthesis, so far only a few papers are available on the relationship between electrochemical deposition parameters and yttrium oxide properties. The formation of Y 2 O 3 by electrodeposition in organic electrolytes containing YCl 3 and a small amount of water was investigated by Matsuda et al 18 Tak and Lee synthesized Y 2 O 3 films on indium tin oxide by cathodic electrodeposition of yttrium hydroxide followed by heat-treatment. 19 In a thermal analysis experiment, they observed that the Y͑OH͒ 3 phase transformed to ␣-Y͑OH͒ 3 at ϳ400°C, and then to Y 2 O 3 above 450°C.…”
