What is Lanthanum Carbonate used for?
Lanthanum Carbonate(LC) is used in medicine as an effective non-calcium phosphate binder. Lanthanum carbonate is also used for the tinting of glass, for water treatment, and as a catalyst for hydrocarbon cracking.
It is also aplied in solid oxide fuel cell applications and certain high-temperature superconductors.
