CAS: 7440-20-2 Molecular weight: 44.96
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.

Package: Under Argon atmosphere or vacuum packaging, 1kg per bag in plastic barrel, also provide small package: 100g, 200g, 500g and other small packaging.
Use: 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.
