Zirconium nitrate is an inorganic chemical compound of zirconium from the group of nitrates .

Extraction and presentation

Zirconium nitrate can be obtained by reacting zirconium (IV) chloride cooled with liquid nitrogen with nitrous oxide . After the vacuum treatment at room temperature, a chloride-free adduct with the composition Zr (NO ₃ ) ₄ · 0.4N ₂ O ₅ · 0.6N ₂ O _{4 is obtained} , which releases the nitrogen oxides only at 100 ° C. in a vacuum and after sublimation in a high vacuum results in pure zirconium nitrate.

properties

Zirconium nitrate is a white solid that appears as long needles after sublimation (just above the melting point), which reacts with hydrocarbons such as butane etc. even at room temperature . It has a monoclinic crystal structure with the space group P 2 ₁ / n (space group no. 14, position 2) . The pentahydrate is soluble in water and ethanol. Template: room group / 14.2

use

Zirconium nitrate can be used to produce pure zirconium (IV) oxide layers.
