It is mined in China and Malaysia. It is given by the ratio of the shear stress to the shear strain.A measure of how difficult it is to compress a substance. Yttrium oxides are a component of the phosphors used to produce the red color in television picture tubes. Investigators are looking into depositing YBCO on top of flexible metal wires, and research into this continues.Apart from this, there are lots of everyday applications for yttrium compounds In its compounds yttrium is always present as the yttrium three plus ion, which means that it is colourless and has no unpaired electrons; therefore it does not have any interesting magnetic or spectroscopic properties of its own. Yttrium Properties. The exact amount is crucial, and tricky to achieve.Other problems include making the YBCO in the right state; a lot of research is going into making thin films of it and finding a way of making it into a continuous wire, rather than just an assembly of crystals packed together that are unable to conduct decent currents.

The higher the value, the larger risk there is to supply.The percentage of the world reserves located in the country with the largest reserves. The up side of this is that yttrium compounds make very good host materials for other lanthanides.The most familiar application lies in the red phosphor in cathode ray tubes, as used in traditional colour TV sets. Or add 1 % of neodymium to YAG and you get the most widely used solid-state laser material. Two American professors, Maw-Kuen Wu and Paul Chu, together with their research groups at the University's of Alabama and Houston, studied yttrium barium copper oxide. This is where the artist explains his interpretation of the element and the science behind the picture.The description of the element in its natural form.The role of the element in humans, animals and plants.Where the element is most commonly found in nature, and how it is sourced commercially.Half of the distance between two unbonded atoms of the same element when the electrostatic forces are balanced.
Singular. Each allotrope has different physical properties.For more information on the Visual Elements image see the Uses and properties section below.A vertical column in the periodic table. Yttrium can rarely be found in nature, as it occurs in very small amounts. The ultimate objective, the Holy Grail, is to find a material that would superconduct at room temperature, but no one has got there yet.There are many possible applications for YBCO; for example MRI scanners could be made to operate more cheaply at a higher temperature using liquid nitrogen coolant. Yet, yttrium was still hiding other elements.In 1843, Carl Mosander investigated yttrium oxide more thoroughly and found that it consisted of three oxides: yttrium oxide, which was white; terbium oxide, which was yellow; and erbium oxide, which was rose-coloured.You're listening to Chemistry in its element brought to you by.This week, the last of the elements discovered in the small town of Ytterby and its compounds appear to have a multitude of uses.Y. You may not further copy, alter, distribute or otherwise use any of the materials from this Site without the advance, written consent of the RSC. Yttrium has a metallic silver sheen. A small amount of yttrium oxide is added to zirconium oxide to make what is known as yttria-stabilized zirconia (also called YSZ). This is approximately the sum of the number of protons and neutrons in the nucleus. The oxides have.Dr. Y is the symbol for the element yttrium.Until about 20 years ago, most scientists had not heard of it, other than vaguely noting where it was in the periodic table, under scandium and above lanthanum. This is made of yttrium oxysulphide, Y2O2S containing a small amount of trivalent europium ions. About 700ppm in the seeds of woody plants.

Yttrium metal is produced by reducing yttrium fluoride with calcium metal.In 1787, Karl Arrhenius came across an unusual black rock in an old quarry at Ytterby, near Stockholm. Similarly, yttrium hosts are often used to accommodate terbium ions, which are green phosphors. Yttrium (Y), chemical element, a rare-earth metal of Group 3 of the periodic table. That has the unusual property of conducting oxide ions, making it very useful in these fuel cells.
Yttrium is usually found only in two different kinds of ores.
