Scandium metal tarnishes in air and burns readily to form scandium (III) oxide, Sc 2 O 3. 4Sc + 3O 2 → 2Sc 2 O 3. Reaction of scandium with water. When finely divided, or heated, scandium metal dissolves in water to form solutions containing the aquated Sc(III) ion together with hydrogen gas, H 2. 2Sc(s) + 6H 2 O(aq) → 2Sc 3+ (aq) + 6OH-(aq) + 3H 2 (g) Reaction of scandium with the ...

The first scandium-based metal-halide lamps were patented by General Electric and initially made in North America, although they are now produced in all major industrialized countries. Approximately 20 kg of scandium (as Sc 2 O 3) is used annually in the United States for high-intensity discharge lamps.
