NeodyMiuM(III) sulfate hyd - Reference Information
| overview | neodymium sulfate, monoclinic crystal. Melting point 1176 ℃, relative density 2.85. Soluble in water. Its anhydrous substance is red needle-like crystals. The pentahydrate can be heated to 300 ℃ to form anhydrous substance. Octahydrate is the most stable among the aqueous salts. Neodymium oxalate is treated with sulfuric acid and obtained by recrystallization. Used to make decolorized glass or glass for welder goggles, etc. |
| preparation method | 1. neodymium oxalate is treated with sulfuric acid and obtained by recrystallization. 2. add 0.30gNd(NO3)3.6H2O to 5ml of water, then add 0.25ml of concentrated sulfuric acid (98% V),0.11 g6-HAD,2ml of ethylene glycol (EG) under stirring conditions, continue stirring at normal temperature for 10min, then place the mixture in a stainless steel reaction kettle lined with 23ml of polytetrafluoroethylene, put it into a 160oC oven, react under spontaneous pressure conditions for 6 hours, and then gradually cool to room temperature. After filtration, deionized water washing and drying at room temperature, light purple transparent bulk crystal neodymium sulfate Nd2(SO4)3(H2O)4 was obtained. |
| application | used to make decolorized glass or glass for welder goggles, etc. Scientific research reagents, biochemical research. |
| use | scientific research reagents, biochemical research mainly used for catalysts, glass and capacitors (capacitors) |
| production method | anhydrous neodymium sulfate can be prepared by heating at a temperature of 200~250 ℃ to completely dehydrate Nd2(SO4)3 · 8H2O. |
