Phase composition-dependent physical and mechanical properties of YbxZr1-xO2-x/2 solid solutions

Journal of Physics and Chemistry of Solids 69 (2008) 805-814

The paper represents a detailed insight into the correlation between changes of the phase composition of crystalline YbxZr1-xO2-x/2 solid solutions and their structural, electrical, mechanical and optical properties. Particularly, the effect of the crystal growth conditions and stabilizer amount in the range of 1.5-13.8 mol% of Yb2O3 are studied in terms of Rietveld analysis of powder X-ray diffraction data, electrical conductivity measured by impedance spectroscopy, absorption coefficient and refractive index measurements, Vickers microhardness (classical technique) as well as the plastic microhardness and effective elastic modulus (DSI-depth-sensing indentation technique). Potential applications of the investigated systems Lire discussed in view of the results obtained. (C) 2007 Elsevier Ltd. All rights reserved.
