Neodymium(III) oxide or neodymium sesquioxide is the chemical compound composed of neodymium and oxygen with the formula Nd 2 O 3. It forms very light grayish-blue hexagonal crystals. [ 1 ] The rare-earth mixture didymium , previously believed to be an element , partially consists of neodymium(III) oxide.
Neodymium(III) oxalate is a rose-coloured crystal which decomposes from its decahydrate to its anhydrous form when heated, and when heated further, decomposes to Nd 2 O 2 C 2 O 4, [12] and then finally obtaining neodymium(III) oxide. [13] Neodymium(III) carbonate is the carbonate of neodymium where neodymium exhibits the +3 oxidation state. It ...
Like its neighbor praseodymium, it readily burns at about 150 °C to form neodymium(III) oxide; the oxide then peels off, exposing the bulk metal to the further oxidation: [14] 4Nd + 3O 2 → 2Nd 2 O 3. Neodymium is an electropositive element, and it reacts slowly with cold water, or quickly with hot water, to form neodymium(III) hydroxide: [21]
Neodymium(III) chloride or neodymium trichloride is a chemical compound of neodymium and chlorine with the formula NdCl 3.This anhydrous compound is a mauve-colored solid that rapidly absorbs water on exposure to air to form a purple-colored hexahydrate, NdCl 3 ·6H 2 O. Neodymium(III) chloride is produced from minerals monazite and bastnäsite using a complex multistage extraction process.
Praseodymium(III) oxide, praseodymium oxide or praseodymia is the chemical compound composed of praseodymium and oxygen with the formula Pr 2 O 3. It forms light green hexagonal crystals. [ 1 ] Praseodymium(III) oxide crystallizes in the manganese(III) oxide or bixbyite structure.
Neodymium(III) carbonate is an inorganic compound, a salt, where neodymium is in the +3 oxidation state and the carbonate ion has charge -2. [1] It has a chemical formula of Nd 2 (CO 3 ) 3 . The anhydrous form is purple-red, [ 2 ] while the octahydrate is a pink solid. [ 3 ]
Neodymium(III) oxalate is the oxalate salt of neodymium, with the chemical formula of Nd 2 (C 2 O 4) 3 in the anhydrous or hydrate form. Its decahydrate decomposes to the anhydrous form when heated, and when heated further, decomposes to Nd 2 O 2 C 2 O 4, [2] finally obtaining neodymium(III) oxide. [3] It dissolves in hydrochloric acid to form ...
Neodymium nickelate can be prepared by dissolving neodymium(III) oxide and nickel(II) oxide in nitric acid, followed by heating the mixture in an oxygen atmosphere. [2] It can also be prepared by pyrolyzing a mixture of nickel nitrate and neodymium nitrate. [2] [3] It decomposes in high temperature (950 °C) by nitrogen: [2] 4 NdNiO 3 → 2 Nd ...
