Chemical & Engineering News Archive, 2003 An account of the high temperature superconductive behavior of yttrium based compounds is presented. The zero-resistivity of a superconductor enables the transmission of electric current without any energy losses. In regard with it, the research account of obtaining a stable superconductive compound composed of yttrium barium copper oxide (YBCO) is ...

Abstract The mass effusion and mass spectrometric methods have been combined to measure over the temperature range 1340 to 2100 K the vapor pressure of solid and liquid yttrium and the partial pressure of yttrium in equilibrium with several metal solutions containing unsaturated and saturated amounts of sesquioxide.

Problems of Atomic Science and Technology, 2023
Emission spectra of excited yttrium particles ejected from the surface of the yttrium metal and yttrium aluminum garnet (YAG) at Ar+ ions are studied. The efficiency of yttrium particles excitation defined from experimental data. The assumption is made that the difference in the excitation efficiency for yttrium atoms and ions is due to the different ...

Investigation of yttrium and yttrium hydride by AES and REELS
Applied Surface Science, 1988Abstract The results of combined investigations by Auger electron spectroscopy (AES) and reflection electron energy loss spectroscopy (REELS) of thin films of yttrium and yttrium hydride are presented. The hydride phase was prepared by exposing evaporated metal films to hydrogen in a high pressure reaction chamber connected to the main UHV vessel ...

Anisotropy of yttrium microhardness
Physica Status Solidi (a), 1981Polar and azimuthal diagrams of the microhardness of yttrium single crystals are constructed. The polar diagram of the microhardness in the (112x) planes with the c axis is close in its form to an ellipsoid of rotation around the [0001] direction with axes 90 and 40 kg/mm2.

Thermal transformation of yttrium hydroxides to yttrium oxides
Thermochimica Acta, 1988Abstract The reaction between aqueous solutions of yttrium salts (chloride and nitrate) at constant concentration and alkaline solutions (sodium and ammonium hydroxides) were investigated under different conditions. As a result, amorphous and hexagonal yttrium hydroxides, Y(OH)3, were formed and in addition monoclinic yttrium hydroxide, α-Y(OH)3, was

Survey of the Mechanical Properties of Yttrium and Yttrium Alloys
1960A survey of the mechanical properties of yttrium and the effects of fifteen different elemental impurities and alloying additions on its tensile strength, ductility, and hardness are described. These properties were found to be relatively insensitive to small additions of most of these elements.

Electronic transitions of yttrium monophosphide
Journal of Molecular Spectroscopy, 2015Abstract The electronic transition spectrum of the yttrium monophosphide (YP) molecule in the near infrared region between 715 nm and 880 nm has been recorded using laser ablation/reaction free-jet expansion and laser induced fluorescence spectroscopy. The YP molecule was produced by reacting laser – ablated yttrium atoms with PH3 gas seeded in argon.
