SCANDIUM CHLORIDE Chemical Properties,Usage,Production

Chemical Properties

white to slightly beige powder

Uses

Scandium chloride (ScCl3): Sc³⁺ + 3Cl^1- → ScCl3. As mentioned, this compound is used in an electrolytic procedure to produce metallic scandium.

Uses

Scandium(III) chloride is a Prins cyclization catalyst. Used to form an intermetallic nickel-scandium compound film by potentiostatic cathodic reduction from molten salt mixtures.

Uses

ScCl₃ can be used in the preparation of lithium salt of anionic scandium tetraborohydride complex (LiSc(BH₄)₄) by forming a ball-milled mixture. LiSc(BH₄)₄ can be used as a potential hydrogen storage material.

General Description

Scandium(III) chloride (ScCl₃) is a scandium halide that can be formed by dissolving scandium oxide in an acid solution and evaporating the resultant solution to dryness.

Safety Profile

Poison by intraperitoneal route. Moderately toxic by ingestion. When heated to decomposition it emits toxic fumes of Cl-. See also SCANDIUM
