Description

Calcium CAS NO 7440-70-2 is a highly reactive, silvery-white metallic element belonging to the alkaline earth metal group. It is a critical raw material for a wide range of industrial processes, valued for its strong reducing properties and its role as an alloying component. This metal is essential for manufacturers in the metallurgical, chemical synthesis, and pharmaceutical industries seeking a high-purity source of elemental calcium for specialized applications.

Application

• Metallurgy & Alloy Production: Used as a deoxidizer, desulfurizer, and degasifier in the production of steel, iron, and non-ferrous metals like aluminum, copper, and lead alloys.
• Chemical Reducing Agent: Employed in the reduction of rare earth metals, thorium, uranium, and zirconium from their oxides or halides.
• Pharmaceutical & Nutraceutical Ingredients: Serves as a source material for the synthesis of calcium salts (e.g., calcium carbonate, calcium citrate) used in dietary supplements and medicinal products.
• Battery Anodes: Investigated for use in advanced battery systems, including calcium-ion and calcium-sulfur batteries, due to its high theoretical capacity and abundance.
• Gettering in Vacuum Tubes: Acts as a getter to remove trace gases (like oxygen and nitrogen) in high-vacuum electronic devices and systems.
• Hydride Production: A key precursor in the manufacture of calcium hydride (CaH2), a powerful drying agent and reducing agent in organic chemistry.

Quality Control

Our Calcium metal is produced and handled under stringent quality management protocols. We offer various grades, including technical and high-purity, with specifications tailored to your application needs. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, metallic impurities, and physical form, ensuring traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its nature as an easily oxidized (store under inert atmosphere) metal, it must be stored under an inert atmosphere such as argon or nitrogen in a cool, dry place. Keep away from moisture, acids, and oxidizing agents. Store at room temperature (15-25°C) in a dedicated, well-ventilated area.
