Calcium Metal for Sale: High-Purity Ca98.5% for Industrial Applications

Calcium metal is a highly reactive, silver-white alkaline earth metal with the symbol Ca and atomic number 20. When exposed to air, it forms a protective nitride-oxide coating. Primarily used as a deoxidizer, desulfurizer, and reducing agent in steelmaking and non-ferrous metallurgy, calcium metal is essential for producing high-quality alloys and special steels.

As a leading calcium metal manufacturer, we supply Ca98.5% pure calcium in various forms—lump, granules, powder, and wire—with a monthly capacity of 3000 metric tons.

Product Details

Physical & Chemical Properties of Calcium Metal

Calcium metal has a relative density of 1.54, a melting point of ~839°C, and a boiling point of 1484°C. It is soluble in acid and liquid ammonia, slightly soluble in alcohol, and insoluble in benzene. High-purity calcium oxidizes slowly in air but burns when strongly heated, forming calcium oxide and nitride. It reacts with water to release hydrogen and is a strong reducing agent.

Safety Note: Calcium is flammable and reacts with water to release flammable gases. Always handle with appropriate safety measures.

Key Applications of Calcium Metal

1. Steelmaking: Deoxidizer, desulfurizer, and inclusion modifier for clean steel production.
2. Non-ferrous metallurgy: Reducing agent for refractory and rare-earth metals.
3. Alloy production: Alloying element for lead-calcium batteries and other alloys.
4. Chemical industry: Dehydrating agent for organic solvents and purifier in oil & gas.
5. Electronics: Getter material in vacuum tubes.
6. Other uses: Medical, construction, and specialty chemical sectors.

How Calcium Metal is Produced

Two primary methods are used to produce calcium metal:

1. Reduction Method: Calcium oxide (from limestone) is reduced by aluminum powder under vacuum, yielding calcium vapor and calcium aluminate.
2. Electrolysis Method: Molten calcium chloride is electrolyzed to produce calcium-copper alloy, which is then vacuum-distilled to obtain pure calcium.

High-purity calcium (>99.9%) is obtained via vacuum distillation, reducing impurities like Cl, Mn, Cu, Fe, and Al to ppm levels.
