Neodymium nitrate
Neodymium nitrate is an inorganic compound with the chemical formula ND(NO3)3. Neodymium nitrate can be obtained by dissolving neodymium oxide, neodymium hydroxide or neodymium carbonate in nitric acid, and the resulting solution can be carefully evaporated to obtain hydrated neodymium nitrate, of which hexahydrate is the most common. By continuing to heat the hexahydrate carefully, anhydrous can be obtained. Neodymium nitrate hydrate loses water first when heated, then decomposes to produce NDONO3, which continues to be heated to obtain neodymium oxide.
Neodymium nitrate contains 6 crystalline water, the appearance is pink crystal, soluble in water and ethanol, the product is deliquescent, and should be stored in a closed and cool place. The molecular formula is ND(NO3)3ยท6H2OMolecular weight: 43824 Neodymium nitratecas no. :14517-29-4
Neodymium nitrate is used in the manufacture of ternary catalysts, glass colorants, magnetic materials, neodymium compound intermediates, chemical reagents and other industries.
Whether it is a laboratory or a business unit, the following principles should be followed when storing rare earth products.
, the principle of sealing. Most rare earth products are sealed and preserved, which is an important principle of product preservation. It mainly includes products with the following properties: products that are easy to deliquescent, reagents that are easy to interact with water vapor, and reagents that are easy to be oxidized or reduced.
, the principle of avoiding light. For rare earth products that are easy to decompose when exposed to light or heat, avoid sunlight and store them in a cool place.
, the principle of isolation. Rare earth products should be kept away from the fire source, and strong oxidants should be separated from substances that are easy to be oxidized.
, the principle of ventilation. The preservation of most rare earth products should follow this principle, especially strong oxidizing agents.
, the principle of low temperature. If the temperature is too high, it is easy to decompose the product, especially in the hot weather in summer, and if necessary, it can be cooled down, such as turning on the air conditioner, blowing the fan, etc.
