Scandium | Chemical Element, Properties & Uses | Britannica
scandium (Sc), chemical element, a rare-earth metal of Group 3 of the periodic table. Scandium is a silvery white, moderately soft metal. It is fairly stable in air but will slowly change its colour from silvery white to a yellowish appearance because of formation of Sc 2 O 3 oxide on the surface. The metal slowly dissolves in diluted acid s ...

Yttrium Oxide
Using scandium oxide, higher conductivity values in comparison with other dopants (i.e., yttrium oxide) can be obtained. The ionic radius of Sc 3+ (0.88 Å) is much closer to the ionic radius of Zr 4+ (0.84 Å) than that of Y 3+ (1.115 Å), which is used as a standard dopant, causing only small distortions of zirconia lattice and resulting in high mobility of vacancies.
