Scandium oxide is amphoteric; lutetium oxide is more basic (although it can with difficulty be made to display some acidic properties), and yttrium oxide is more basic still. [58] Salts with strong acids of these metals are soluble, whereas those with weak acids (e.g. fluorides, phosphates, oxalates) are sparingly soluble or insoluble.
Scandium-stabilized zirconia enjoys a growing market demand for use as a high-efficiency electrolyte in solid oxide fuel cells. [citation needed] The USGS reports that, from 2015 to 2019 in the US, the price of small quantities of scandium ingot has been $107 to $134 per gram, and that of scandium oxide $4 to $5 per gram.

In all four halides, the scandium is 6-coordinated. They can be prepared by reacting scandium oxide or scandium hydroxide with the corresponding acid: [3] Sc(OH) 3 + 3 HX → ScX 3 + 3 H 2 O. The halides are Lewis acids; for example, ScF 3 dissolves in a solution containing excess fluoride ion to form [ScF 6] 3−. The coordination number 6 is ...
Scandium(III) oxide or scandia is a inorganic compound with formula Sc 2 O 3.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 Are Nitric Oxide Supplements? First things first: Nitric oxide supplements don't actually contain nitric oxide, but they do contain ingredients that stimulate nitric oxide production in the body.
