Yttrium iodide is a binary inorganic compound, a salt of yttrium and hydroiodic acid with the formula YI
3.[2][3] The compound forms colorless crystals, soluble in water.
Synthesis
[edit]1. Heating yttrium and iodine in an inert atmosphere:
2. Heating yttrium oxide with ammonium iodide:
It can also be obtained by reacting yttrium oxide or yttrium hydroxide with hydroiodic acid.
Physical properties
[edit]Yttrium iodide forms colorless flaky crystals. The crystal structure is that of the BiI
3 structure type.[4]
It dissolves well in water and ethanol. Does not dissolve in diethyl ether.
It also occurs as a tri- and hexahydrate.[5]
Applications
[edit]A precursor for YBCO superconducting materials in a lower temperature preparation.[6]
