Kev siv Lanthanum Carbonate
Lanthanum Carbonate, yog raw khoom rau FCC catalyst, iav, dej kho thiab tshuaj FOSRENOL. Lanthanum-nplua nuj Tsis tshua muaj Lub Ntiaj Teb Carbonate tau siv dav rau kev tawg cov tshuaj tiv thaiv hauv FCC catalysts, tshwj xeeb tshaj yog los tsim cov roj av siab-octane los ntawm cov roj hnyav hnyav. Lanthanum Carbonate tau pom zoo ua tshuaj (Fosrenol, Shire Pharmaceuticals) kom nqus tau cov phosphatein ntau dhau ntawm lub raum tsis ua haujlwm.
