Core Physical and Chemical Properties
Structural & Thermal Properties
Lanthanum Carbonate maintains stable physical and chemical properties under normal temperature and sealed storage environments, with no spontaneous decomposition or deterioration. Its most prominent advantage is controllable high-temperature calcination performance. During high-temperature heating, it can undergo steady and complete thermal decomposition, fully converting into high-purity Lanthanum Oxide (La₂O₃) without carbon residue or lattice defects. The decomposition process is mild and uniform, which effectively guarantees the high purity, compactness and stable performance of downstream oxide products. Compared with other lanthanum precursors, it has a moderate calcination temperature threshold and higher conversion efficiency, perfectly adapting to industrial continuous calcination and mass production.
Chemical & Reaction Properties
Chemically, Lanthanum Carbonate possesses stable and moderate chemical activity. It is insoluble in water and organic solvents, endowing it with excellent storage stability and transportation safety. It can completely react with various dilute inorganic acids to generate high-purity lanthanum salt solutions, providing high-quality lanthanum sources for customized synthesis of lanthanum chloride, lanthanum nitrate, lanthanum acetate and other derivatives. With low hygroscopicity and strong anti-carbonation ability, it maintains stable component content in conventional processing environments, effectively reducing impurity introduction and improving the repeatability of industrial batching and experimental synthesis.
