Terbium(III) nitrate explained

Terbium(III) nitrate is an inorganic chemical compound, a salt of terbium and nitric acid, with the formula . The hexahydrate crystallizes as triclinic colorless crystals with the formula . It can be used to synthesize materials with green emission.^[1]

Preparation

Terbium(III) nitrate can be prepared by dissolving terbium(III,IV) oxide in a mixture of aqueous and solution.^[2]

Terbium(III) nitrate can be obtained by reacting terbium(III) oxide with nitric acid and crystallizing then drying the crystals with 45~55% sulfuric acid to obtain the hexahydrate.^[3]

Properties

It reacts with to produce along with its basic carbonate.^[4] It forms in with excess nitrate anions.^[5]
