Kushandiswa kweLanthanum Carbonate
Lanthanum Carbonate, zviwanikwa zveFCC catalyst, girazi, kurapwa kwemvura uye mushonga weFOSRENOL. Lanthanum-yakapfuma Rare Earth Carbonate yakashandiswa zvakanyanya mukupwanya maitiro muFCC catalysts, kunyanya kugadzira high-octane peturu kubva kune inorema crude oil. Lanthanum Carbonate yakatenderwa semushonga (Fosrenol, Shire Pharmaceuticals) kutora yakawandisa phosphate muzviitiko zvekupedzisira-danho renal kukundikana.
