Samarium carbides are prepared by melting a graphite-metal mixture in an inert atmosphere. After the synthesis, they are unstable in air and need to be studied under an inert atmosphere. [36] Samarium monophosphide SmP is a semiconductor with a bandgap of 1.10 eV, the same as in silicon, and electrical conductivity of n-type. It can be prepared ...
Samarium carbides are prepared by melting a graphite-metal mixture in an inert atmosphere. After the synthesis, they are unstable in air and are studied also under inert atmosphere. [13] Samarium monophosphide SmP is a semiconductor with the bandgap of 1.10 eV, the same as in silicon, and high electrical conductivity of n-type. It can be ...
Samarium(III) oxide (Sm 2 O 3) is a chemical compound. Samarium oxide readily forms on the surface of samarium metal under humid conditions or temperatures in excess of 150°C in dry air. Similar to rust on metallic iron, this oxide layer spalls off the surface of the metal, exposing more metal to continue the reaction.
Samarium(III) chloride, also known as samarium trichloride, is an inorganic compound of samarium and chloride.It is a pale yellow salt that rapidly absorbs water to form a hexahydrate, SmCl 3. 6H 2 O. [1] The compound has few practical applications but is used in laboratories for research on new compounds of samarium.
Samarium(III) oxalate is an inorganic compound, a salt of samarium and oxalic acid with the formula Sm 2 (C 2 O 4) 3. [1] The compound does not dissolve in water, forms a crystalline hydrate with yellow crystals.
