Neodymium carbonate - Preparation Method
Open Data Verified Data
solvent extraction method: the raw material is the rare earth back extraction solution after extracting lanthanum with dimethyl heptyl methylphosphonate (P350), which is concentrated to contain total Re. Rare earth solution of Oy 150g/L, HNO 30. 3mol/L. The first step with di (2-ethylhexyl) phosphoric acid (P204)-kerosene solution of neodymium samarium grouping, the second step with trialkylmethylamine chloride (N263)-kerosene solution extraction neodymium, an acidic solution of neodymium nitrate was obtained. The product is neutralized with ammonia, added ammonium bicarbonate to precipitate neodymium carbonate at a lower temperature, filtered, washed, centrifuged and dried.

Neodymium carbonate - Reference Information
| application | neodymium carbonate can be used to make ternary catalysts, magnetic materials, neodymium compound intermediates, chemical reagents, etc. |
| Preparation | Neodymium carbonate can be obtained from the hydrolysis of neodymium trichloroacetate: 2 Nd(C2Cl3O2)3 3 H2O → Nd2(CO3)3 6 CHCl3 3 CO2 Another method is to react neodymium chloride and ammonium bicarbonate in water. |
| toxicity | see cerium oxide products. |
| use | used as decolorant and colorant for glass. used for glass decolorant, colorant and capacitor materials, etc. scientific research reagents, biochemical research |
| production method | solvent extraction method raw material is rare earth stripping solution after lanthanum extraction from dimethyl heptyl methylphosphonate (P350), concentrated into total RexOy150/L,. FINO30.3 mol/L rare earth solution. The first step uses bis (2-ethylhexyl) phosphoric acid (P2O4)-kerosene solution to group neodymium samarium, and the second step uses trialkylmethylamine chloride (N263)-kerosene solution to extract neodymium to obtain acid Neodymium nitrate solution. Neutralize with ammonia water, add ammonium bicarbonate at a lower temperature to precipitate neodymium carbonate, filter, wash, centrifuge, and dry the product. |
