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.
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(III) nitride is a chemical compound of neodymium and nitrogen with the formula NdN in which neodymium exhibits the +3 oxidation state and nitrogen exhibits the -3 oxidation state. It is ferromagnetic, like gadolinium(III) nitride , terbium(III) nitride and dysprosium(III) nitride . [ 3 ]
Neodymium(III) nitrate and ammonia water will react to produce neodymium(III) hydroxide: [4] Nd(NO 3) 3 + 3 NH 3 ·H 2 O → Nd(OH) 3 ↓ + 3 NH 4 NO 3. If the amount of Nd(NO 3) 3 is 40g/L, the amount of ammonia water needed is 0.50 mol/L. The ammonia water is mixed into the Nd(NO 3) 3 solution at the speed of 1.5mL/min, and polyethylene ...
Neodymium(III) acetate is an inorganic salt composed of a neodymium atom trication and three acetate groups as anions where neodymium exhibits the +3 oxidation state. [2] It has a chemical formula of Nd(CH 3 COO) 3 although it can be informally referred to as NdAc because Ac is an informal symbol for acetate. [ 8 ]
