It is used to make the high-temperature superconductor YBCO (yttrium barium copper oxide) and it is used to produce phosphors, which provide the red color in color television tubes. It is a silvery, ductile, fairly reactive metal that is easily combustible, reacts with oxygen in water to release hydrogen. Molar magnetic susceptibility: 5.921×10-9 m3/mol, Density: 4.472 g/cm3 (In solid) 4.24 g/cm3 (In Liquid) A crystal lattice is a repeating pattern of mathematical points that extends throughout space. Yttrium is found in lathanoid minerals and the extraction of the yttrium and the lanthanoid metals from the ores is highly complex. Yttrium metal was first isolated in 1828 when Friedrich Wöhler heated anhydrous yttrium (III) chloride with potassium. Specific heat: 298 J/(kg K) The three most common basic crystal patterns are: This website was founded as a non-profit project, build entirely by a group of nuclear engineers. Biological role: Its soluble salts are mildly toxic. Yttrium is found in most rare-earth minerals. Yttrium has a silvery-metallic lustre. WebElements: THE periodic table on the WWW [www.webelements.com] Periodic Table of the Elements. 9.9×10-7% (In Sun) Shear modulus: 25.6 GPa Space Group Number: 194, Electronegativity: pauling scale: 1.22 Element category: Transition metal 2 Y (s) + 3 Cl2 (g) → 2 YCl3 (s) (Yttrium (lll) chloride) Lanthanoids comprise the 15 metallic chemical elements with atomic numbers 57 through 71, from lanthanum through lutetium. Yttrium-aluminium garnet (Y3Al5O12) is used in lasers that can cut through metals, It is also used in white LED lights. Isotope-90Y is exists in equilibrium with its parent 90Sr (isotope of Strontium), a product of nuclear explosions. 7. Yttrium chemical symbol is Y, atomic number is 39 and its atomic weight is 88.9 g/mol. Yttrium is often used in alloys, increasing the strength of aluminum and magnesium alloys. Yttrium was discovered in the year 1794 by Johan Gadolin. ), and shape. Bulk modulus: 41.2 GPa The relative atomic mass of Yttrium is 88.90585 u. Vicker hardness: 904 MPa 19×10-5% (In Meteorites) CAS Number: CAS7440-65-5 The Cookies Statement is part of our Privacy Policy. Yttrium oxide is added to the glass which is used to make camera lenses to make them heat and shock resistant. E. Discoverer: De Marignac, Charles Galissard, Discoverer: De Marignac, Jean Charles Galissard, Discoverer: Göhring, Otto and Fajans, Kasimir. Finely divided yttrium is very unstable in air. Namded after Ytterby, a village in Sweden near Vauxholm. Web. Yttrium is the first d-block element in the fifth period. Some people might just have known that it was one of 4 chemical elements named after the small Swedish town of … The density of Yttrium is 4450 kg/m3. These elements, along with the chemically similar elements scandium and yttrium, are often collectively known as the rare earth elements.

A Electrical resistivity: α poly: 596 nΩ∙m Initially, the metals are extractedas salts from the ores by extraction with sulphuric acid (H2SO4), hydrochloric acid (HCl), and sodium hydroxide (NaOH). Young’s modulus: 63.5 GPa Yttrium was discovered by Johan Gadolin (FI) in 1794. m. Electrical resistivity and its converse, electrical conductivity, is a fundamental property of a material that quantifies how strongly it resists or conducts the flow of electric current. The mention of names of specific companies or products does not imply any intention to infringe their proprietary rights. Critical point (Superconducting point): 1.3 K (-271.85 oC, -457.33 oF), A Magnetic type: Paramagnetic Yttrium can be used as a catalyst for ethylene polymerization reactions. Interactive periodic table showing names, electrons, and oxidation states. Of these, one is stable, 89Y. YIG is also exceptionally efficient as both a transmitter and transducer of acoustic energy. The chemical symbol for Yttrium is Y. It is used as a catalyst in ethylene polymerization. Yttrium is a silvery white, moderately soft, ductile metal. What is Discovery of the Neutron - Definition, What is Structure of the Neutron - Definition. Poisson ratio: 0.243 4d1. Yttria-- earth containing yttrium-- was discovered by Gadolin in 1794. The metal readily reacts with diluted {Date of access}.
The name semiconductor comes from the fact that these materials have an electrical conductivity between that of a metal, like copper, gold, etc. Exposed surfaces form oxide film. Each episode, we take a look at the fascinating true stories behind one element on the periodic table.
