Applicatio:
Yttrium nitratis applicatur in ceramicis, vitreis, et electronicis. Gradus munditiae altae sunt praecipuae materiae pro vinculis tri- nexibus Rare Terrae phosphororum et Yttrium-Iron-Garnets, quae efficacissimae proin filamenta sunt. Yttrium nitratum est valde aqua solubile Yttrium crystallinum fons pro usui compatibilis cum nitratis et inferioribus (acidicis) pH. Usus in industriis ut catalystas ternaria, yttrium tungsten electrodes, materias ceramicas, intermedia yttrium compositorum, chemicorum. scaturigo yttrium, dicitur mesophase surfactum fabricare secundum yttrium; adsorbent vel quasi praecursorem pro substantiis functionis opticis et nano scalae materiae compositae carbonis tunicae.

Processus productionisyttrium nitrate sub calefacto, yttrium oxydi concentratum in acido nitrico contracto leviter calefacto diluitur. Urite yttrium oxydatum in 900 pro 3 horis, refrigera et solve in solutione acidi nitrici 1:1. Moderari pH solutionis in fine reactionis esse 3-4. Distillant solutionem sub pressura reducta in syrupum et lente crystallize ad locus temperatus. Recrystallize bis. Cum recrystallizing, parva quantitate yttrium nitrate adjici debet ut semen ad crystallum hexahydratum nitrate obtinendum yttrium.
