Scandium chloride is a kind of inorganic compound, at room temperature and pressure is a grayish white solid, soluble in water but insoluble in anhydrous ethanol. It has a high melting point and density, relatively stable chemical properties, not easy to react with water, but can react with some alkaline substances to generate the corresponding salts. In chemical reactions, scandium chloride can react with a variety of substances to produce different chemical products. Scandium chloride is widely used in the field of materials science, and can be used to manufacture catalysts, alloys, ceramics and optical materials, etc., which can improve the hardness, corrosion resistance and thermal stability of materials. In addition, scandium chloride is also an important raw material for the manufacture of other scandium compounds, and is widely used in chemical reagents and other industrial fields.
