What Is Lanthanum Carbonate?
Lanthanum carbonate is a chemical compound used primarily in its hydrated form. It’s known for forming various hydrates, including monohydrate, dihydrate, tetrahydrate, and octahydrate, alongside its anhydrous form. Classified as a deleterious substance in some regions, it necessitates careful handling due to its regulatory status under multiple safety and environmental laws.
Uses of Lanthanum Carbonate
Lanthanum carbonate octahydrate is utilized in medical treatments for hyperphosphatemia in chronic kidney disease patients by binding phosphate ions in the digestive tract to reduce blood phosphorus levels. It’s also prescribed in veterinary medicine for cats with renal failure. Beyond healthcare, lanthanum carbonate finds applications in glass coloring, water treatment, catalysts for hydrocarbon decomposition, and the manufacture of materials for fuel cells.
Properties of Lanthanum Carbonate
The anhydrous form of lanthanum carbonate is a white powder, soluble in acid but hardly soluble in water. The octahydrate form shares similar solubility characteristics and is used for its pharmacological properties.
Other Information on Lanthanum Carbonate
Lanthanum carbonate hydrate is produced by reacting lanthanum oxide with nitric or hydrochloric acid and then adding sodium carbonate. When handling lanthanum carbonate, precautions should be taken to avoid skin contact and inhalation of dust. It should be stored in a cool, dark place in a sealed container to prevent exposure to strong oxidizers and direct sunlight.
