Description

Lanthanum Oxalate is a high-purity inorganic salt of lanthanum, a rare earth element, with the CAS registry number 537-03-1. This compound is valued for its role as a critical precursor in the synthesis of advanced materials, particularly high-performance lanthanum oxide ceramics and phosphors. It is essential for manufacturers and R&D facilities in the electronics, catalysis, and specialty glass industries seeking consistent quality and reliable supply for their production processes.

Application

• Ceramic & Glass Manufacturing: A key precursor for producing lanthanum oxide (La₂O₃), used in optical glasses, camera lenses, and high-refractive-index glass fibers.
• Catalyst Production: Serves as a starting material for catalysts used in petroleum refining (fluid catalytic cracking) and automotive exhaust systems.
• Phosphor & Luminescent Materials: Used in the synthesis of phosphors for lighting, display technologies (LEDs, plasma panels), and X-ray intensifying screens.
• Electronic Components: A raw material for manufacturing dielectric ceramics in multilayer ceramic capacitors (MLCCs) and other electronic devices.
• Chemical Synthesis & Research: Employed as a reagent in laboratory research and the synthesis of other lanthanum compounds and coordination complexes.
• Specialty Coatings: Used in formulations for coatings that require specific thermal or chemical resistance properties.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture. Keep away from strong acids and strong oxidizing agents.
