| Use |
Mainly used as a colorant for glass and ceramics, a raw material for the manufacture of neodymium metal and a raw material for strong magnetic neodymium iron boron. Neodymium-doped yttrium aluminum garnet is used in laser technology. It is also used to make neodymium glass. Because of its excellent absorption of ultraviolet and infrared, it is used to make precision instruments. It is the raw material for making neodymium metal and various neodymium alloys and permanent magnet alloys. Can be used as glass purple colorant. It is used as the coloring and magnetic materials for TV bulbs, glassware, the raw materials for manufacturing metal neodymium and the raw materials for strong magnetic neodymium iron boron. |
| Application | The application and research of neodymium oxide in the field of catalysis are also gradually expanded, such as the synthesis of carboxylic acid esters and the amination of fatty alcohols. Nano neodymium oxide has good catalytic activity. Nano neodymium oxide, as a rare earth nano material, added to magnesium or aluminum alloy can improve the strength, chemical book and corrosion resistance of magnesium or aluminum alloy in high temperature environment. This high-performance material is widely used in the field of aerospace industry. In medical treatment, nano neodymium oxide can be used to make nano yttrium aluminum garnet laser. This laser can produce short wave laser and can replace ordinary scalpel in special occasions. |
| production method |
The extraction method takes rare earth chloride solution as raw material and extracts it with P204 kerosene HCl rcl3 system. The rare earth mixture is divided into light, medium and heavy rare earth groups, precipitated with oxalic acid, separated, dried and burned to prepare neodymium oxide. The ND2 (C2O4) 3 → Nd2O3 + 3co2 + 3Co NdFeB waste recovery method is to add 1:4h2so4 to the neodymium iron boron raw material (containing 30.02% neodymium) after alkaline washing to remove oil dirt until no bubbles are generated, control the liquid-solid ratio of 4:1, and the end pH is 1. After filtration, 2mol / L NaH2PO4 is added to the filtrate until the precipitation is completed, and ND2 (SO4) 3 is completely generated in the chemical book. At this time, the pH value is 2.3, but Fe2 + does not produce precipitation. The precipitate was filtered and washed with 0.1mol/lh2so4 to remove iron. The precipitate is heated to 140 ℃ with 12mol / LNaOH solution to form hydroxide, washed with water to remove ph43 -, and then neutralized, dissolved, filtered, concentrated and crystallized in 1:4 to form neodymium sulfate crystal with high purity. Then precipitate with (NH4) 2CO3, filter, wash and dry, and calcine at 80 ℃ for 1h to obtain pure Nd2O3 with content ≥ 99.0%. The total recovery of neodymium is more than 90.00%.
