Properties
Yttrium(III) nitrate hexahydrate loses crystallized water at relatively low temperature. Upon further heating, basic salt YONO3 is formed.{{cite journal|last1=Zhuang|first1=R.F.|last2=Qiu|first2=J.B.|last3=Zhu|first3=Y.P.|title=A study on reaction mechanism in preparation of Y-Ba-Cu-O superconducting material from the thermoreaction method of nitrates|journal=Journal of Solid State Chemistry|volume=86|issue=1|year=1990|pages=125–128|issn=0022-4596|doi=10.1016/0022-4596(90)90122-E}} At 600 C, the thermal decomposition is complete. Y2O3 is the final product.{{cite journal|last1=Xu|first1=F.M.|last2=Zhang|first2=Z.J.|last3=Shi|first3=X.L.|last4=Tan|first4=Y.|last5=Yang|first5=J.M.|title=Effects of adding yttrium nitrate on the mechanical properties of hot-pressed AlN ceramics|journal=Journal of Alloys and Compounds|volume=509|issue=35|year=2011|pages=8688–8691|issn=0925-8388|doi=10.1016/j.jallcom.2011.05.110}}
Y(NO3)3·3TBP is formed when tributyl phosphate is used as the extracting solvent.{{cite journal|last1=Scargill|first1=D.|last2=Alcock|first2=K.|last3=Fletcher|first3=J.M.|last4=Hesford|first4=E.|last5=McKay|first5=H.A.C.|title=Tri-n-butyl phosphate as an extracting solvent for inorganic nitrates—II Yttrium and the lower lanthanide nitrates|journal=Journal of Inorganic and Nuclear Chemistry|volume=4|issue=5–6|year=1957|pages=304–314|issn=0022-1902|doi=10.1016/0022-1902(57)80012-8}}
Uses
Yttrium(III) nitrate is mainly used as a source of Y3+ cations. It is a precursor of some yttrium-containing materials, such as Y4Al2O9, YBa2Cu3O6.5+x and yttrium-based metal-organic frameworks.
