  • Scandiumdoped zinc cadmium oxide as a new stable ntype oxide

    Scandiumdoped zinc cadmium oxide (Scdoped ZnCdO) is proposed as a new ntype oxide thermoelectric material. The material is sintered in air to maintain the oxygen stoichiometry and avoid instability issues. The successful alloying of CdO with ZnO at a molar ratio of 1 : 9 significantly reduced the thermal.

    The substance discovered by Nilson was not pure scandium metal, but a compound of scandium and oxygen —scandium oxide (Sc 2 O 3 ). Today, companies that use scandium often buy the oxide rather than the pure metal. Scandium metal is a silverywhite solid with a slight pink or yellow tint when exposed to air.

    Feb 24, 2015 Scandium is a silverwhite metal that develops a light yellow/pink cast when exposed to air. Scandium has a much higher melting point than aluminum, which is why it is of interest to spacecraft designers. Like other transition metals, it is susceptible to weathering and will slowly dissolve in dilute acids.
