Yttrium is mostly dangerous in the working environment, due to the fact that damps and gasses can be inhaled with air. This can cause lung embolisms, especially during long-term exposure. Yttrium can also cause cancer with humans, as it enlarges the chances of lung cancer when it is inhaled.
Yttrium(III) Nitrate Hexahydrate, Y(NO3)3 · 6H2O, is widely used for optics, ceramics, glass, electronics and superconducting applications. It also can be used as catalyst in Bignelli reaction, synthesis of some supramolecules and organic condensation products.
Yttrium Nitrate (Yttrium(III) Nitrate Hexahydrate) is a highly water soluble crystalline Yttrium source for uses compatible with nitrates and lower (acidic) pH. All metallic nitrates are inorganic salts of a given metal cation and the nitrate anion.
