Gadolinium nitrate
Preparation of gadolinium nitrate: gadolinium carbonate and excess nitric acid. Gadolinium nitrate is synthesized by the reaction of gadolinium carbonate with excess nitric acid. Gadolinium nitrate is a chemical substance with the molecular formula GD(NO3)36H2O. White crystals, density 2406g per cm3, melting point 91 degrees Celsius, soluble in water and alcohol, easy to deliquescent in humid air.
Molecular formula: GD(NO3)3ยท6H2O
Molecular weight: 45126
cas no. :94219-55-3
Appearance: white or colorless crystals, soluble in water and alcohol, deliquescent, closed storage.
Uses: used in the manufacture of gadolinium ferroalloy materials, gadolinium compound intermediates, chemical reagents and other industries.
Storage precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30, and the relative humidity should not exceed 80%. Keep the container tightly sealed. It should be stored separately from reducing agents, alkalis, alcohols, alkali metals, etc., and should not be mixed. The storage area should be equipped with emergency response equipment for spills and suitable containment materials.
Transportation precautions: railway tank car loading, of which lead tank car is used to convey 98% concentrated nitric acid, dilute nitric acid should be transported or stored in stainless steel or FRP reinforced plastic tank car or storage tank. A small amount is packed in acid-resistant ceramic jars or glass bottles, with a net weight of 33-40kg per jar. Concentrated nitric acid is sealed with acid-resistant mud, and dilute nitric acid is sealed with gypsum. Each jar is packed in a sturdy wooden box lined with fine cinders or fine slag for easy transportation. It should be evident on the packaging"Corrosive substances"Sign. Because there is an oxide film on the surface of aluminum, which plays a passivation role and is economical, aluminum is an ideal container for nitric acid. Personal protection ** direct contact is prohibited, and acid and alkali resistant gloves, masks, and other labor protection supplies should be worn during operation.
