Yttrium is mostly dangerous in the working environment, due to the fact that damps and gasses can be inhaled with air. The oxide was later discovered and named yttria.

It reacts with water decomposing it to release hydrogen gas, and it reacts with mineral acids. Yttrium is often used in alloys, increasing the strength of aluminum and magnesium alloys. (3) (These were to be typical properties of all the rare earth metal oxides.). (5), Ultra-pure yttrium-90 is used for cancer therapy. Yttrium is also used in lasers, ceramics, camera lenses. With water animals yttrium causes damage to cell membranes, which has several negative influences on reproduction and on the functions of the nervous system. Zirconium was discovered by Martin Heinrich Klaproth, a German chemist, while analyzing the composition of the mineral jargon (ZrSiO 4) in 1789.Zirconium was isolated by Jöns Jacob Berzelius, a Swedish chemist, in 1824 and finally prepared in a pure form in 1914. It is used to make the high-temperature superconductor YBCO (yttrium barium copper oxide). All rare chemicals have comparable properties. Stanford Advanced Materials (SAM) Corporation is a global supplier of various sputtering targets such as metals, alloys, oxides, ceramic materials. We now know Gadolin’s yttria was impure; in addition to yttrium oxide, it contained eight other rare earth metal oxides. Yttrium wires and rods are used in electronics and solar energy.

In 1787, Carl Axel Arrhenius found a mineral near this town and named it ytterbite. Despite their name, rare-earth elements are rather plentiful around the world.

In the decades after Antoine Lavoisier developed the new chemistry built on the concept that earths could be reduced to their elements, the discovery of a new earth (with name ending in "a") was regarded as equivalent to discovering the element within. They tend to be strong but pliable, therefore, some of these metals are widely used for wires.

(1), (2), Johan Gadolin received a ytterbite sample from Arrhenius and carried out a detailed analysis of it in 1794, in Finland.

Yttrium is used as a catalyst in ethylene polymerization.

Yttrium-90 is produced by high-purity separation from strontium-90, a fission product of uranium in nuclear reactors. exploring a quarry near Ytterby, a small town near Sweden’s capital city, Stockholm, he discovered an unusual black rock.

Yttrium is named after Ytterby, Sweden, where a mineral containing it was discovered in a quarry.

Yttrium iron garnets are extremely efficient transmitters and transducers of acoustic energy. Phone: +971 4 429 5853 e-mail: info@lenntech.com, Copyright © 1998-2020 Lenntech B.V. All rights reserved, Plant Inspection & Process Optimalisation, Separation and Concentration Purification Request. Yttrium-90, a radioactive isotope, is used in treatments for various cancers and is used in precision medical needles to sever pain-transmitting nerves in the spinal cord.

Most of its compounds are colorless. Yttrium iron (Y3Fe5O12), yttrium aluminium (Y3Al5O12) and yttrium gadolinium garnets possess interesting magnetic properties. Yttrium also dissolves oxygen gas in relatively high concentrations.

Yttrium is found in the rare-earth mineral monazite, of which it makes 2.5%, and in smaller quantities in other minerals such as barnasite, fergusonite and smarskite. Isotopes: Yttrium has 25 isotopes whose half-lives are known, with mass numbers 79 to 103. The substance they identified as alumina was actually the oxide of another new element, beryllium. A fourth oxide, ytterbium oxide, was identified in 1878. Yttrium is usually found only in two different kinds of ores. Unfortunately Gadolin and Ekeberg did not realize that their alumina analyses were incorrect.

Yttrium can rarely be found in nature, as it occurs in very small amounts. These were discovered separately in later years; these metals were: erbium , terbium , ytterbium , scandium , thulium , holmium dysprosium , and lutetium .

Yttrium oxide is used in ceramic and glass formulations.

Yttrium is fairly stable in air, because it is proteced by the formation by the formation of a stable oxide film on its surface, but oxidizes readily when heated. John D. Corbett, Frank Harold Spedding A Biographical Memoir., National Academy Press 2001, p22. Johan Gadolin discovered yttrium's oxide in Arrhenius' sample in 1789, [5] an Anders Gustaf Ekeberg named the new oxide yttria . Yttrium wires and rods are used in electronics and solar energy.

Yttrium is a highly crystalline iron-gray, rare-earth metal. Yttrium can be found in most of the rare earth minerals, but has never been discovered in the Earth’s crust as a freestanding element.

Source: Yttrium occurs in uranium ores and is present in nearly all the ‘rare earth’ minerals. Yttrium will gradually accumulate in soils and water soils and this will eventually lead to increasing concentrations in humans, animals and soil particles.

Water soluble compounds of yttrium are considered to be slightly toxic, while its insoluble compounds are considered to be non-toxic. (2). Ytterbite was renamed gadolinite (a yttrium-iron-beryllium-silicate mineral) in 1800 by Martin Klaproth in honor of John Gadolin. In 1787, while the Swedish chemist Carl Axel Arrhenius exploring a quarry near Ytterby, a small town near Sweden’s capital city, Stockholm, he discovered an unusual black rock. Yttrium’s properties are very similar to those of the rare earth elements of the lanthanide series. During the analysis, Gadolin isolated the yttrium from the mineral.
The rare-earth elements include yttrium, scandium and 15 lanthanides. This can cause lung embolisms, especially during long-term exposure. The yellow-brown ore xenotime can contain as much as 50% yttrium phophate (YPO4) and is mined in Malaysia. Yttrium oxide in glass makes it heat- and shock-resistant, and is used for camera lenses. The mine had been developed in the early 18th century as a result of the mineral requirements of the local pottery industry. Bengt Geijer, the inspector of mines in Stockholm, carried out a rough analysis of ytterbite.

Chemistry Dictionary | Birth of the Elements | Tools | Periodic Table | Citing Chemicool | About | Privacy | Contact. Yttrium was the first rare earth element to be discovered. (3), Gadolin’s results were confirmed in 1797 by Swedish chemist Anders Ekeberg.

Yttrium is a highly crystalline iron-gray, rare-earth metal. It can also enter the environment when household equipment is thrown away. Ekeberg suggested the name yttria for the oxide of the new earth metal and hence the new metal was named yttrium.

The silver-colored lining is an alloy of nickel,chromium, aluminum and yttrium. Yttirum. Yttrium can be found in most of the rare earth minerals, but has never been discovered in the Earth’s crust as a freestanding element. Yttrium is fairly stable in air, because it is proteced by the formation by the formation of a stable oxide film on its surface, but oxidizes readily when heated. Ytterby is the site of a quarry which yielded many unusual minerals containing rare earths and other elements. Preparation of Molybdenum Sputtering Targets by Powder Metallurgy, Advantages of Sputtering Deposition and Vacuum Evaporation, Advantages of Investing in Platinum and Palladium Precious Metals, Silicon Wafer: 4 Types of Wet Cleaning Method. Yttrium is also used in lasers, ceramics, camera lenses, sputtering targets and dozens of other items. He thought that he had discovered a new mineral, and sent some specimens to Johan Gadolin, a Finnish mineralogist, for analysis. Shavings or turnings of the metal can ignite in air when they exceed 400 °C.

Yttrium never occurs in nature as a free element. They have become indispensible in the manufacturing of cell phones and other technology. Its anly stable isotope, 89 Y, is an aa its anly naiturally occurrin isotope. Yttrium oxide is widely used for making compounds such as YVO4europium and YVO4europium phosphors in television tubes.

The transition metals are the metallic elements that serve as a bridge, or transition, between the two sides of the table.

Yttrium metal was first obtained in 1828, in Berlin, by Friedrich Wöhler as a gray powder by heating anhydrous yttrium (III) chloride with potassium.

.

It is also used as a deoxidizer for non-ferrous metals such as vanadium. In 1787, Carl Axel Arrhenius foond a new mineral near Ytterby in Swaden an named it ytterbite , efter the veelage. Robert Charles Gallo (/ ˈ ɡ ɑː l oʊ /; born March 23, 1937) is an American biomedical researcher. The mineral was later named gadolinite in Gadolin’s honor, and Yttrium was named Ytterby from where the mineral was discovered. The rare-earth elements include yttrium, scandium and 15 lanthanides. Abundance earth’s crust: 33 parts per million by weight, 7.6 parts per million by moles, Abundance solar system: 10 parts per billion by weight, 0.1 parts per billion by moles. Ekeberg then confirmed beryllium oxide was present in ytterbite and alumina was absent. The transition metals are the metallic elements that serve as a bridge, or transition, between the two sides of the table. Yttrium is a transition metal with the atomic number of 39 and the chemical symbol Y.

Yttrium doped with europium is used to produce phosphors, which provide the red color in color television tubes. Yttrium usually exists as a trivalent ion, Y3+, in its compounds.

, yttrium is considered one of the transition metals (yellow in the pic). Accordingly, yttrium is classified as one of the rare earth elements. Required fields are marked *, Yttrium is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a “. Yttrium metal has found some use alloyed in small amounts with other metals and It is used to increase the strength of aluminium and magnesium alloys.

It was discovered in 1794 by Johan Gadolin. Yttrium is also one of the seventeen rare-earth elements.
