Dec 10, 2014· The NC State research team combined lithium, magnesium, titanium, aluminum and scandium to make a nanocrystalline high-entropy alloy that has low density, but very high strength. “The density is comparable to aluminum, but it is stronger than titanium alloys,” says Dr. Carl Koch, Kobe Steel Distinguished Professor of Materials Science and
Nov 18, 2016· Selenium (Emsley 1991, 2001; Anthoni 2006; Anders and Grevesse 1989; McDonough 2005) is a semi-metal that exists in two allotropic forms as a silvery metal and as a red amorphous powder; the former is produced from the latter by heat.The metal consists of spirals of linked selenium atoms and the red form has stacked rings each made up of eight selenium atoms.
Selenium Properties. Selenium is a Block P, Group 16, Period 4 element.The number of electrons in each of Selenium's shells is 2, 8, 18, 6 and its electron configuration is [Ar] 3d 10 4s 2 4p 4. Selenium was discovered and first isolated by Jöns Jakob Berzelius and Johann Gottlieb Gahn in 1817. It is produced from selenide which is found in many sulfide ores.

Heavy metals are generally defined as metals with relatively high densities, atomic weights, or atomic numbers.The criteria used, and whether metalloids are included, vary depending on the author and context. In metallurgy, for example, a heavy metal may be defined on the basis of density, whereas in physics the distinguishing criterion might be atomic number, while a chemist would likely be

Sep 24, 2020· Welcome to Scandium International Mining Corporation. Scandium International Mining Corp. (SCY) owns an interest in the Nyngan Scandium Project, located in New South Wales, Australia, approximately 500 kilometers northwest of Sydney.
Jun 11, 2014· Both single crystals and pure bulk phases of three new scandium selenium/tellurium oxides, Sc2(SeO3)2(SeO4), Sc2(TeO3)(SeO3)(SeO4), and Sc2(TeO3)3, have been synthesized through hydrothermal and solid-state reactions. X-ray diffractions were used to determine the structures and confirm the phase purities of the reported materials. Isostructural Sc2(SeO3)2(SeO4) and …
Scandium can be recovered from thortveitite or extracted as a by-product from uranium mill tailings (sandy waste material). Metallic scandium can be prepared by reducing the fluoride with calcium metal. It can also be prepared by electrolysing molten potassium, lithium and scandium chlorides, using electrodes of tungsten wire and molten zinc.
The rare-earth elements, also called the rare-earth metals or (in context) rare-earth oxides, or the lanthanides (though yttrium and scandium are usually included as rare-earths) are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals. Scandium and yttrium are considered rare-earth elements because they tend to occur in the same ore deposits as the lanthanides and

Oct 22, 2009· Scandium – Light weight bicycle parts (rims in particular) Selenium – Photocopiers Titanium – Hip implants Zinc – Pennies. The most misunderstood element is Iodine. I think it speaks for all the halogens which are constantly accused of being, “one electron shy of a full shell.”
Indeed, the toxicity level of selenium to humans was established only 20 years ago by studies of Chinese victims of selenium poisoning, selenosis, who grew corn on selenium rich coal rocks. Selenosis has some lovely symptoms: a garlic odor on the breath, hair loss, sloughing of nails, fatigue, irritability, and eventually cirrhosis of the liver
Processed scandium oxide, a white powder, is stable at ambient temperature and is the standard scandium form for commerce. Despite scandium’s scarcity and high cost, interest in the metal is high and multiple high value commercial uses have been developed. Of particular interest is the alloy of scandium into aluminum metal products.
S. Cotton, in Comprehensive Coordination Chemistry II, 2003 18.104.22.168.3 Alkoxides. Scandium alkoxides represent a class of compound as yet with poorly characterized structures. Attempted synthesis of the isopropoxide Sc(OPr i) 3 results in the production 78 of a pentanuclear compound [Sc 5 O(OPr i) 13], similar to those formed by yttrium, ytterbium, and indium.It has the structure [Sc 5 (μ 5-O
