[edit] Chemistry
Lanthanum carbonate is used as a starting material in lanthanum chemistry, particularly in forming mixed oxides, for example
- for production of lanthanum strontium manganite, primarily for solid oxide fuel cell applications;
- for production of certain high-temperature superconductors, such as La2-xSrxCuO2.
[edit] Human and veterinary medicine
Lanthanum carbonate is used in medicine as a phosphate binder[1]. As a medication it is sold under the trade name Fosrenol by the pharmaceutical company Shire Pharmaceuticals. Fosrenol is the largest of all pills filled in community pharmacies. Sometimes patients forget that fosrenol is not swallowed whole, but instead should be chewed. This has led to severe choking. It is prescribed for the treatment of hyperphosphatemia, primarily in patients with chronic kidney disease. It is taken with meals and binds to dietary phosphate, preventing phosphate from being absorbed by the intestine. For cats suffering from hyperphosphatemia it is available under the trade name Renalzin by Bayer Animal Health.[2]
[edit] Other applications
Lanthanum carbonate is also used for the tinting of glass, for water treatment, or as a catalyst for hydrocarbon cracking.
