Applicazioni

It acts as a precursor for the preparation of yttrium oxide nano particles and for nanoscale coatings of carbon composites. It is an effective yttrium source for the preparation of yttrium-based surfactant mesophases which are used as adsorbing agents and in optically functional materials. It is used in optics, ceramics, glass, electronics, and superconducting materials. It has been reported as a reusable catalyst in Bignelli reaction for the synthesis of heterocycles such as pyrimidin-2-ones. It is a powerful catalyst for the synthesis of some supramolecules such as calix[4]resorcinarenes, 1,8-dioxooctahydroxanthenes, 2-amino-4H-chromenes, and several other organic condensation products. Silica-supported yttrium nitrate hydrate acts as a heterogeneous catalyst for the preparation of 2-Amino-4H-Chromenes in water.

Note

Stable compound. Incompatible with strong reducing agents and strong acids.
