Lanthanum chloride (LaCl₃) is an inorganic rare earth compound with multiple industrial applications. The heptahydrate form (LaCl₃·7H₂O) is the most common commercial variant, appearing as white crystalline granules or blocks that exhibit deliquescent properties. This compound serves as a critical raw material for catalyst production, rare earth metal smelting, and energy storage device manufacturing.
Our RECL-LA grade lanthanum chloride heptahydrate features a purity of 99.95% (LaCl₃/REO), making it suitable for demanding industrial processes. With 20,000 units currently in stock, we can fulfill large-volume orders for manufacturing facilities and research institutions worldwide. The crystalline form ensures consistent performance in various production environments and simplifies handling during industrial operations.

Lanthanum chloride serves as a primary precursor for manufacturing fluid catalytic cracking (FCC) catalysts used in petroleum refineries. These catalysts enhance cracking efficiency and increase light oil yield from crude oil feedstocks. The 99.95% purity grade ensures consistent catalyst performance and extends catalyst service life in industrial refining operations.
As a raw material for rare earth extraction, lanthanum chloride enables the production of high-purity metallic lanthanum through electrolytic reduction processes. It also facilitates the enrichment of mixed rare earth metals from ore concentrates, supporting the global supply chain for rare earth materials.
Lanthanum chloride contributes to the production of hydrogen storage alloys used in nickel-metal hydride (Ni-MH) batteries. These alloys exhibit hydrogen adsorption properties and cycling stability, making them suitable for various energy storage applications including portable electronics and hybrid electric vehicles.
In laboratory and industrial settings, lanthanum chloride acts as a precursor for synthesizing other rare earth compounds, including organic lanthanide complexes. It also finds use as an analytical reagent, magnetic material component, and chemical additive in specialized manufacturing processes.
The primary distinction between these two forms lies in their water content and concentration. Anhydrous lanthanum chloride (LaCl₃) contains no water molecules, providing the highest lanthanum concentration. This form is typically used in specialized industrial applications such as petroleum cracking catalyst production and moisture-sensitive chemical synthesis processes.
Heptahydrate lanthanum chloride (LaCl₃·7H₂O) is the most widely available commercial form. It dissolves readily in water and offers easier handling compared to the anhydrous form. This variant is preferred for water treatment applications, pool maintenance, and general industrial processes where solubility and cost-effectiveness are important considerations.
Lanthanum chloride reacts rapidly with dissolved orthophosphates in water to form lanthanum phosphate (LaPO₄), an insoluble solid precipitate. By reducing phosphate levels to below 100 ppb, it limits the nutrient availability for algae growth, helping to maintain clear water in swimming pools and industrial water systems.
When used according to recommended guidelines, lanthanum chloride is compatible with most aquatic organisms. However, the fine white precipitate formed during phosphate removal may irritate fish gills or be ingested by filter-feeding invertebrates. To minimize risks, add diluted solution slowly through a 10-micron filter sock and ensure proper skimmer operation to remove precipitate immediately. Monitor alkalinity levels, as overdosing may cause a slight decrease in KH values.
Anhydrous lanthanum chloride contains no water and offers higher lanthanum concentration, making it suitable for moisture-sensitive industrial processes. Heptahydrate lanthanum chloride contains seven water molecules per formula unit, is more soluble in water, and is easier to handle for general industrial and water treatment applications.
Our RECL-LA grade 99.95% lanthanum chloride heptahydrate is available in bulk quantities with 20,000 units currently in stock. We offer flexible packaging options to meet the specific requirements of industrial manufacturing facilities and research institutions.
