What is the correct name for Sc2O3?
Scandium(III) oxide
Scandium(III) oxide | Sc2O3 – PubChem.
Why is scandium oxide basic?
Hint: In scandium oxide, there are two atoms of scandium and three atoms of oxygen. So, the formula of scandium oxide is Sc2O3. If it can react with acid as well as a base then the compound is said to be amphoteric.

Is scandium oxide a gas?
Scandium oxide Chemical Properties,Uses,Production A high melting white solid used in high-temperature systems (for its resistance to heat and thermal shock), electronic ceramics, and glass composition.
What is scandium used for?
Scandium is mainly used for research purposes. It has, however, great potential because it has almost as low a density as aluminium and a much higher melting point. An aluminium-scandium alloy has been used in Russian MIG fighter planes, high-end bicycle frames and baseball bats.
What is scandium oxide used for?
It is one of several oxides of rare earth elements with a high melting point. 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).
What is scandium price?
Price for pure scandium fluctuates between $4,000 and $20,000 per kilogram.
How is scandium used in everyday life?
Scandium is used in aluminum-scandium alloys for aerospace industry components and for sports equipment such as bicycle frames, fishing rods, golf iron shafts and baseball bats. Scandium iodide is used in mercury vapor lamps, which are used to replicate sunlight in studios for the film and television industry.
Is scandium harmful to humans?
Health effects of scandium Scandium is mostly dangerous in the working environment, due to the fact that damps and gasses can be inhaled with air. This can cause lung embolisms, especially during long-term exposure. Scandium can be a threat to the liver when it accumulates in the human body.
How is scandium oxide made?
Reactions. Scandium oxide is the primary form of refined scandium produced by the mining industry, making it the start point for all scandium chemistry. Scandium oxide reacts with most acids upon heating, to produce the expected hydrated product. For example, heating in excess aqueous HCl produces hydrated ScCl3·nH2O.
