Scandia, Sc2O3

Scandium sesquioxide or scandia, Sc2O3, is obtained by igniting the hydroxide, carbonate, oxalate, nitrate, sulphate, etc., of scandium. It is a white powder of density 3.864, and specific heat 0.1530 (0° to 1000). It is diamagnetic, the magnetic susceptibility being –0.05×10-6 c.g.s. electromagnetic units per unit mass. It dissolves slowly in cold, more readily in hot dilute acids, and very readily in hot concentrated acids, scandium salts and water being produced.
