Description

Samarium Carbonate is an inorganic salt of the rare earth element samarium, known for its utility as a high-purity precursor material. This compound is essential for producing specialty catalysts, phosphors, and advanced ceramic materials where precise chemical composition is critical. It serves key roles in the electronics, glass polishing, and chemical research industries, enabling innovations in optics and material science.

Application

• Catalyst Precursor: Used in the synthesis of catalysts for organic synthesis and petroleum refining.
• Phosphor Manufacturing: Acts as a key raw material in the production of specialized phosphors for display screens and lighting.
• Ceramic & Glass Additive: Imparts specific optical and structural properties to advanced ceramics and specialty glass.
• Chemical Research & Synthesis: Serves as a high-purity starting material for synthesizing other samarium compounds and organometallic complexes.
• Polishing Compounds: A component in fine polishing powders for optical lenses and electronic components.
• Nuclear Applications: Utilized in certain control rod and shielding materials due to samarium's neutron absorption properties.

Quality Control

Our Samarium Carbonate is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including assay and impurity profile analysis, to ensure it meets the high standards required for industrial and research applications. Certificates of Analysis (COA) detailing purity, heavy metal content, and other critical parameters are available upon request.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can affect product quality and handling.
