Presentation Transcript

  1. Scandium 5E 27,28,38,41

  2. Scandium Properties • Scandium metal soft metal • Silvery appearance • Scandium exists naturally exclusively as the isotope 45Sc • Sc3+ • Phase: Solid • Density: 2.985 g·cm−3 • Melting point: 1541 °C • Boiling point: 2836 °

  3. Scandium Characteristics • Sc2O3And Sc(OH)3 Amphoteric Sc(OH)3 + 3 OH− → Sc(OH)3-6 Sc(OH)3 + 3 H+ + 3 H2O → [Sc(H2O)6]3+ • Non-Toxic

  4. Scandium Application (Al2Sc3) • Aluminium-Scandium Alloys • Minor aerospace industry components • Around 0.1 - 0.5 % content of Scandium • Baseballs Bat • Bicycle frames and Component

  5. Scandium Application (Sc2O3) • Scandium Oxide • High-intensity Discharge Lamps

  6. Scandium Application (ScI3+NaI) • Scandium Iodide + Sodium Iodide • Modification of Lamps • Modification of TV cameras

  7. Scandium Application (46Sc) • Radioactive Isotope 46Sc • Oil refineries (煉油廠) as a tracing agent
