Oxygen Self-Diffusion in Y2O3 and Y2O3-ZrO2 Solid Solution
1985Yttrium oxide (Y2O3) C-type cubic rare-earth-oxide crystal structure. This structure is described as a modified fluorite-type cubic structure where one fourth of the anion sites are vacant and regularly arranged. Some studies concerning the point defect disorder (Tallan and Vest, 1966; Odier et al., 1971; Rifflet et al., 1975) and self-diffusion ...

The deoxidizing ability of yttrium has not been sufficiently studied, although it has a high affinity for oxygen. In ferrous metallurgy, yttrium is often used in the form of an alloy with silicon. The effect of each of the components of the silicoyttrium alloy on the process of liquid metal deoxidation can be established by studying the Fe‒Y‒Si‒O ...

Surface Y2O3 layer formed on air exposed Y powder characterized by XPS
, 2020X-ray photoelectron spectroscopy (XPS) was performed to characterize the air formed Y2O3 surface layer on yttrium powder. Prior to XPS measurements, x-ray diffraction was performed to confirm the presence of Y2O3.

Phase relations in the Y2O3-Ga2O3 system were studied by the anneal-and-quench technique in air within 1000–2300°C, and a phase diagram was plotted. Three compounds were found to form: Y3GaO6, Y4Ga2O9, and Y3Ga5O12; the temperature and concentration bounds of stability were determined for these compounds. Indexing results for Y3GaO6 are given.

Synthesis and luminescence of spherical Y2O3:Eu3+ and Y2O3:Eu3+/Bi3+ particles
Journal of Materials Science: Materials in Electronics, 2016Y2O3:Eu3+ and Y2O3:Eu3+/Bi3+ particles with spherical morphology are synthesized by microwave-assistant hydrothermal process. The results show that cubic phase Y2O3:Eu3+ and Y2O3:Eu3+/Bi3+ particles with uniform size and spherical shape are obtained. The doping Eu3+ and Bi3+ ion have no influence on the phase and morphology of samples.

Phase relations in the systems ZrO2Y2O3Nd2O3 and ZrO2Y2O3CeO2
Materials Research Bulletin, 1986Abstract The phase relations of ZrO 2 Y 2 O 3 Nd 2 O 3 and ZrO 2 Y 2 O 3 CeO 2 systems have been studied at 1100–1600°C. The single region of the fluorite phase was intensively examined using the relation between lattice parameter and composition.

Wear, 2019
The present study is based on erosion wear analysis of WC-Co-Cr powder thermally sprayed on super-duplex stainless steel (SDSS) 2507. A high-velocity oxy-fuel (HVOF) process was used to deposit the WC-Co-Cr thermal spraying powder.
