High purity 99.999% Scandium Metal Sc CAS 7440-20-2 For Aluminium Scandium Alloy

Scandium is a soft, silver-white transition metal with good ductility and catalytic properties. Scandium has important applications in many fields. In the aerospace industry, scandium alloys are used to manufacture high-temperature engine parts and turbine blades because of their high strength, hardness and high temperature resistance. In iron and steel smelting, scandium can significantly improve the strength, hardness and corrosion resistance of steel. In addition, scandium is also used in the manufacture of special glass, lightweight high-temperature alloy and rare earth permanent magnet materials, such as Ndfeb permanent magnets, which can improve the thermal stability and magnetic properties of the material. The chemical properties of scandium are active, and it is easy to react with oxygen, carbon dioxide and water in the air, so it needs special preservation. Despite the complexity of its extraction and processing, scandium's wide application and unique properties make it a valuable resource in materials science and industry. With the progress of science and technology, more application potential of scandium is being continuously explored and utilized.

Description

Scandium can be made into various forms: Scandium foil, Scandium sheet, Scandium block and Scandium powder. Scandium is the most advanced transition metal, but in terms of discovery, scandium is later than its neighbors on the periodic table. Even in rare earth, scandium is not found earlier. The reason for its later discovery is simple, the content is low, and the content in the crust is about 0.0005%. In addition, it is very difficult to separate rare earth elements, so it is not easy to find scandium from mixed mineral deposits. Scandium is a light silvery white metal. Its chemical properties are also very active. It can react with hot water to generate hydrogen. Therefore, scandium metal is sealed in the bottle and protected by argon gas, otherwise scandium will quickly form a dark yellow or gray oxide layer and lose the shiny metallic luster.

Used

It has been widely used in the doping of aluminum alloy. As long as a few thousandths of scandium is added to aluminum, a new phase of Al3Sc will be formed, which will increase the recrystallization temperature of the alloy by 150-200 ℃, and the high temperature strength, structural stability, welding performance and corrosion resistance are significantly improved, and the embrittlement phenomenon easy to occur in long-term operation at high temperature can be avoided. High strength and high toughness aluminum alloy, new high-strength and corrosion-resistant weldable aluminum alloy, new high temperature aluminum alloy, high-strength and neutron irradiation resistant aluminum alloy, etc., have very attractive development prospects in aerospace, aviation, ships, nuclear reactors, light vehicles and high-speed trains.
