Synthesis and Thermal Properties of Cerium-Dysprosium Oxide

Abstract

The paper presents results of investigation on synthesis and characterization of cerium-dysprosium oxide. The input powders -dysprosium oxide Dy 2 O 3 and cerium oxide CeO 2 -were mixed so as to obtain equimolar ratio of cations, milled in alcohol and synthesized via solid state reaction process at 1350°C under 15MPa in vacuum for 2h. The microstructure, phase composition and thermal properties were analyzed. The obtained material was multiphase. Non-stoichiometric compounds were identified. Thermal diffusivity of investigated material decreased in the temperature range of 25-1000°C from 0,71 to 0,45 mm 2 /s.

Properties of Polydisperse Tin-doped Dysprosium and Indium Oxides

“…Therefore, studies of the dysprosium oxide doping with various elements are of considerable practical interest. The use of such dopants as Ce, Rh, Zr, and Hf [2][3][4][5] is well known, but there are practically no data on doping of dysprosium oxide with Sn. At the same time, the most widely studied oxide material used in electronics is indium oxide doped with tin (ITO), which is a solid solution of indium oxide (III) and tin (IV).…”
