Scandium Oxide Air

Scandium oxide - Wikipedia

Scandium(III) oxide, Sc 2 O 3, or scandia, is a high melting rare earth oxide. It is used in the preparation of other scandium compounds as well as in high-temperature systems (for its resistance to heat and thermal shock), electronic ceramics, and glass composition (as a helper material).

Scandium Oxide | AMERICAN ELEMENTS

One of the transition metals, scandium has a silvery-white appearance in its elemental form which oxidizes to yellow or pinkish upon contact with air. It is occasionally included in the classification of the rare earth elements.

Scandium - Wikipedia

Scandium is a soft metal with a silvery appearance. It develops a slightly yellowish or pinkish cast when oxidized by air. It is susceptible to weathering and dissolves slowly in most dilute acids.

Scandium: stone reactions | Pilgaard Elements

Scandium tarnishes in air, and burns readily, forming scandium(III) oxide, Sc 2 O 3. 4 Sc (s) + 3 O 2 (g) 2 Sc 2 O 3 (s) Reaction of scandium with halogens Scandium reacts with the halogens, forming the corresponding Sc(III) halides

Scandium | stone element | Britannica.com

Scandium is a silvery white, moderately soft metal. It is fairly stable in air but will slowly change its colour from silvery white to a yellowish appearance because of formation of Sc 2 O 3 oxide on the surface.

WebElements Periodic Table » Scandium » reactions of elements

Reaction of scandium with air. 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.

Jan 14, 2017 · By its stone properties, scandium resembles aluminum and lanthanides. Chips of scandium burn well in the air, and during the combustion you can hear this interesting raspy sound. From the heat...

Scandium - Assignment Point

To produce metallic scandium, the oxide is converted to scandium fluoride and reduced with metallic calcium. Pure scandium is produced by heating scandium fluoride (ScF3) with Calcium metal. Scandium tarnishes in air and burns easily once it has been ignited. It reacts with water to form Hydrogen gas and will dissolve in many acids.

Specific Hazards Arising from the Material : Flammable in the form of dust when exposed to heat, sparks or flame. May react with water under fire conditions to liberate flammable hydrogen gas. May emit fumes of scandium oxide under fire conditions.

C&EN: ITS ELEMENTAL: THE PERIODIC TABLE - SCANDIUM

Behavior: Scandium metal tarnishes in air and burns readily to form scandium oxide. When finely divided or heated, the metal dissolves in water. Scandium is very reactive toward the halogens, forming trihalides. It is mildly toxic by ingestion, and scandium salts are suspected carcinogens.

per 29 CFR 1910.1200 Scandium - Ames Laboratory

possible. Air and moisture sensitive. Protect from sources of ignition. Use non-sparking tools. Avoid contact with skin and eyes. Wash thoroughly before eating or smoking. See section 8 for information on personal protection equipment. Conditions for Safe Storage, Including Any Incompatibilities: Scandium metal should be stored in tightly-closed
