Applicationem Lanthanum Carbonatis
Lanthanum carbonatum, materia rudis FCC catalyst, vitri, aquae curatio et medicina FOSRENOL. Lanthanum-dives Rare Terrae Carbonatis late adhibitae sunt ad motus in FCC catalysts crepescentes, praesertim ad gasolinum altum octanum fabricandum ex oleo crudo gravi. Lanthanum carbonas probatum est ut medicamentum (Fosrenol, Comitatus Pharmaceuticorum) ad hauriendum excessum phosphatein casus ofendi-scenici defectus renalis.
