Neodymium oxide Chemical Properties,Usage,Production

Chemical Properties Neodymium Oxide, Nd2O3 is a blue-grey powder that is composed of the rare earth neodymium and oxygen. hygroscopic; absorbs atmospheric CO2; hexagonal; has slightly red fluorescence. Water insoluble, soluble in acids. It has special properties that make it very useful to the glass and ceramics industries. Neodymium Oxide gives a good aqua color in most glaze bases at 1-2%. At 4-7% it gives a pleasant lavender/grape color that appears as a different color under different artificial light sources. It is very strongly affected by iron, particularly in oxidation, giving a reliable perfect neutral transparent gray. Avoid trace iron impurities to achieve the brightest blue and lavender colors.
Physical properties Blue powder; hexagonal crystals; fluoresces red; density 7.24 g/cm³; melts around 1,900°C; practically insoluble in water, 30 mg/L at 75°C; dissolves in acids.
Uses Neodymium oxide (Nd2O3) is a light-blue powder used to color glass and as a pigment for ceramics. It is also used to make color TV tubes.
Uses Neodymium(III) oxide is an inorganic compound containing inner transition metal neodymium from lanthanides series in +3 oxidation state and oxide in 2:3 ratio. It adopts a hexagonal crystal structure. It is also known as neodymium oxide, neodymiumtrioxide, neodymium(3+)oxide, neodymium sesquioxide and dineodymiumtrioxide. It used as ceramic capacitors, coloring glass, carbon arc-light electrodes, color TV tubes, dehydrogenation catalyst, (65%) To counteract color of iron in glass.
Production Methods Neodymium oxide is produced from the two principal rare earth minerals, monazite, and bastnasite. The oxide is obtained as an intermediate in the recovery of neodymium metal (See Neodymium).
The oxide also may be formed by thermal dissociation of neodymium oxalate, hydroxide or carbonate:
Nd₂(C₂O₄)₃ → Nd₂O₃ + 6CO₂
2Nd(OH)₃ → Nd₂O₃ + 3H₂O
Nd₂(CO₃)₃ → Nd₂O₃ + 3CO₂.
Reactions The anhydrous oxide absorbs moisture from the air at ambient temperatures forming hydrated oxide. The oxide also absorbs carbon dioxide from air, forming neodymium carbonate.
Neodymium oxide dissolves in strong mineral acids forming corresponding neodymium salts:
Nd2O3 + 3H2SO4 → Nd2(SO4)3 + 3H2O
Reactions with acetic and other organic acids produce corresponding salts. When heated with ammonium chloride at 300 to 400°C, the oxide converts to chloride liberating ammonia and water:
Nd2O3 + 6NH4Cl → 2NdCl3 + 6NH3 + 3H2O
When heated with hydrogen fluoride, the product is neodymium fluoride:
Nd2O3 + 6HF → 2NdF3 + 3H2O
The oxide is reduced to neodymium metal when heated with hydrogen, carbon monoxide, or other reducing agents.
Flammability and Explosibility Non flammable
reaction suitability reagent type: catalyst
core: neodymium
Toxicology Neodymium oxide is belong to a rare earth metal. These metals are moderately to highly toxic. The symptoms of toxicity of the rare earth elements include writhing, ataxia, labored respiration, walking on toes with arched back and sedation.
Safety Profile Low toxicity by ingestion.
Purification Methods Dissolve it in HClO4, precipitate it as the oxalate with doubly recrystallised oxalic acid, wash it free of soluble impurities, dry it at room temperature and ignite it in a platinum crucible at higher than 850o in a stream of oxygen. It is a blue powder. [Tobias & Garrett J Am Chem Soc 80 3532 1958.]
