Synthesis
Reaction of ytterbium and nitric oxide in ethyl acetate:
:{{chem2 | Yb + 3 N2O4 -> Yb(NO3)3 + 3 NO↑ }}
Reaction of ytterbium hydroxide and nitric acid:
:{{chem2 | Yb(OH)3 + 3 HNO3 -> Yb(NO3)3 + 3 H2O↑ }}
Physical properties
Ytterbium(III) nitrate forms colorless hygroscopic crystals.
Forms crystalline hydrates of the composition {{chem2|Yb(NO3)3*nH2O}}, where n = 4, 5, or 6.{{cite web |title=Ytterbium(III) nitrate pentahydrate |url=https://pubchem.ncbi.nlm.nih.gov/compound/Ytterbium_III_-nitrate-pentahydrate |publisher=pubchem.ncbi.nlm.nih.gov |access-date=19 August 2021 |language=en}}
==Chemical properties==
The hydrated ytterbium nitrate thermally decomposes to form YbONO3 and decomposes to ytterbium oxide upon further heating.
Application
Ytterbium(III) nitrate hydrate is used for nanoscale coatings of carbon composites.{{cite web |title=12901 Ytterbium(III) nitrate hydrate, 99.9% (REO) |url=https://www.alfa.com/en/catalog/012901/ |publisher=Alfa Aesar |access-date=19 August 2021}}
Also used to obtain metallic ytterbium and as a chemical reagent.
Used as a component for the production of ceramics and glass.
