Description

Lanthanum Carbonate is an inorganic salt of the rare earth element lanthanum, widely recognized for its high phosphate-binding capacity. This property makes it a critical material for managing phosphate levels in industrial and specialized applications. It is essential for manufacturers in the pharmaceutical, catalyst, and advanced materials sectors who require a reliable, high-purity source for consistent product performance.

Application

• Pharmaceutical Active Ingredient: Primary use as a phosphate binder in medications for the control of hyperphosphatemia in patients with chronic kidney disease.
• Catalyst & Catalyst Support: Used in petroleum refining, automotive exhaust catalysts, and various organic synthesis reactions due to its unique Lewis acidity and thermal stability.
• Specialty Glass & Optics: A key component in the production of high-refractive-index optical glasses, camera lenses, and fiber optics to improve optical properties.
• Electronic Ceramics: Employed in the manufacture of multilayer ceramic capacitors (MLCCs), piezoelectric materials, and other electronic components.
• Water Treatment: Acts as an effective precipitant for the removal of phosphates and fluorides from industrial wastewater.
• Research & Development: Serves as a starting material or reagent in chemical synthesis and materials science research within academic and industrial laboratories.

Quality Control

Our Lanthanum Carbonate is manufactured under a strict quality management system. Production batches are tested against rigorous in-house specifications to ensure high chemical purity, consistent physical properties, and low levels of heavy metal impurities. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical characteristics is provided with every shipment to guarantee traceability and compliance with your requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in a dry environment to prevent caking and degradation. Keep away from strong acids.
