Lanthanum Chloride or Lanthanum(III) chloride (LaC13) is an inorganic salt of the rare-earth element Lanthanum. As the first element of the lanthanide series, it is universally valued for its stable †3 oxidation state and its strong Lewis acid character. Whether supplied as the moisture-sensitive Anhydrous powder (10099-58-8), the highly stable Heptahydrate Crystals (10025-84-0), or in a Solution form, the common factor is the highly reactive Lat ion. This ion is utilized extensively in Electronic & Specialty Grade Materials for its ability to bind to anions (like phosphate) and to catalyze organic reactions. We are leading & trusted Lanthanum Chloride suppliers with various grades in the United States and worldwide, offering high purity Lanthanum Chloride that meets US quality and safety standards, with reliable lead times and global supply capability.

For bulk FCC use, you typically reference- Heptahydrate CAS (10025-84-0). This form is the most stable and cost-effective solid, readily soluble, and safe for large-scale handling, balancing high purity needs with economic viability.
Anhydrous form is required for moisture-sensitive reactions because it guarantees minimal water content. Because Lat ion acts as a strong Lewis acid catalyst, trace water from the Hydrate form will quickly quench or poison the reaction, leading to failure or poor yields.
Chinese REE refiners often use the Solution grade (10099-58-8 solute) or the Generic Hydrate CAS (20211-76-1). These forms are easier to handle in complex solvent extraction and refining processes, providing a lower-cost feedstock for producing final high-purity La products.
The difference is the amount of water chemically bound to the LaC13 molecule. 10099-58-8 is the LaCl molecule with zero water (anhydrous). 10025-84-0 is the Heptahydrate (7 water molecules). 20211-76-1 is for a Generic/Indefinite Hydrate (varying water content).
Primary consideration for the Solution grade is its corrosive nature (due to its acidity and chloride content). While LaCl3 itself is a low-toxicity REE salt, the solution concentration requires correct DOT classification for hazardous liquids to ensure safe transport and handling.
Researchers often prefer the Heptahydrate Crystal (10025-84-0) because it is highly stable, can be easily weighed with high precision, and has a lower surface area than powder, minimizing moisture absorption during measurement preparation. This ensures the best possible consistency for high-end material synthesis.
