Scandium nitrate is an inorganic chemical compound of scandium from the group of nitrates .

Extraction and presentation

Scandium nitrate can be obtained by reacting scandium with dinitrogen tetroxide .

{\ displaystyle \ mathrm {Sc + 3 \ N_ {2} O_ {4} \ longrightarrow Sc (NO_ {3}) _ {3} +3 \ NO}}

The anhydrate can also be obtained by reacting scandium chloride with nitrous oxide . The colorless tetrahydrate can be prepared by reacting scandium hydroxide with nitric acid .

properties

Scandium nitrate is a white solid that is soluble in water and ethanol . Several hydrates are known of the compound , such as the di-, tri- and tetrahydrate. The tetra and trihydrates have a monoclinic crystal structure . If the tetrahydrate is heated in air, it is converted into the dihydrate at 50 ° C. However, this already converts to a compound with the structure Sc ₄ O ₃ (NO ₃ ) ₃ · 6.5H ₂ O at 60 ° C. At 140–220 ° C, Sc ₄ O ₅ (NO ₃ ) _{3 is formed} .
