Scandium is mainly used for research purposes. It has, however, great potential because it has almost as low a density as aluminium and a much higher melting point. An aluminium-scandium alloy has been used in Russian MIG fighter planes, high-end bicycle frames and baseball bats.
Jun 16, 2020 Selenium is not produced in the body, but it is needed for proper thyroid and immune system function. Selenium is used to treat or prevent selenium deficiency. Selenium has been used in alternative medicine as an aid to treat Hashimoto's thyroiditis (an autoimmune disorder of the thyroid), and to treat high cholesterol.

Scandium-46, which is a radioactive isotope of the element, is used in oil refineries, where it plays the role of a tracing agent. The compound scandium triflate acts as a catalyst in organic chemistry. Scandium can also be used for the purpose of polishing glass. Scandium, in
The biggest use of selenium is as an additive to glass. Some selenium compounds decolourise glass, while others give a deep red colour. Selenium can also be used to reduce the transmission of sunlight in architectural glass, giving it a bronze tint. Selenium is used
Selenium can convert AC electric current to DC current and is used in such converters. It is the active ingredient in dandruff-prevention shampoos, and is a cutting agent in rubber. Selenium can remove color from glass, or it can add a red color to it. It is also used in alloys, especially with steel. Biological Benefits
Jul 07, 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.

Scandium is the first element in the fourth period of the transition element. It is the 42nd most abundant element found in the Earths crust. Scandium is a soft, lightweight, silvery-white metal with the chemical symbol Sc.
Uses of selenium. The most common use of selenium is in the production of glass. Due to the fact that selenium causes a red color in glass it can be used to create a red color in glass. It can also be used to cancel out the green or yellow tints caused by other impurities during the glassmaking process.
Aluminum-scandium alloys are used for things like very expensive bicycle frames, baseball bats, and even a line of light-weight handguns. (Amazingly, two separate readers have written in to me about this last application, both commenting that the guns are very uncomfortable to shoot because the light weight results in a strong kickback.)

Scandium is a chemical element with the symbol Sc and atomic number 21. A silvery-white metallic d-block element, it has historically been classified as a rare-earth element, together with yttrium and the lanthanides.It was discovered in 1879 by spectral analysis of the minerals euxenite and gadolinite from Scandinavia.. Scandium is present in most of the deposits of

Uses for Scandium. Aerospace and lighting are the two areas where scandium finds itself being used most, but it is not cheap. For instance, the cost of pure scandium
Selenium was discovered by Jöns Jacob Berzelius, a Swedish chemist, in 1817 after analyzing an impurity that was contaminating the sulfuric acid (H 2 SO 4) being produced at a particular factory in Sweden.Originally believing the material was tellurium, Berzelius eventually realized that it was actually a previously unknown element.Selenium occurs in minerals such as eucairite

Alloys of scandium and aluminum are used in some kinds of athletic equipment, such as aluminum baseball bats, bicycle frames and lacrosse sticks. It is expected ...
Selenium’s photovoltaic and photoconductive properties contribute to its use in photocopying, toning of photographic prints, photocells, light meters, and solar cells. A semi-conductive material below its melting point, selenium is also used in electronic applications. Application Notes.
Mar 26, 2020 There are five sub-shells, but only four of them are used by naturally occurring elements: s, p, d and f. Each sub-shell accommodates a certain number of electrons. Sub-shells s, p, d and f hold a maximum of two, six, 10 and 14 electrons, respectively. In selenium, the first energy level has two electrons in sub-shell s.
