Product Overview
Calcium lump is a silvery-white light metal with excellent chemical reactivity, a soft texture, and a density of 1.54 g/cm³. With a melting point of 839±2°C and a boiling point of 1484°C, calcium has high reactivity at room temperature, reacting with water and acids to release hydrogen gas. The surface of calcium lumps forms a thin oxide and nitride layer in the air, effectively preventing further corrosion.
Features
- Soft texture, low density, moderate melting and boiling points.
- Strong chemical reactivity, reacts with water and acids to release hydrogen gas.
- Forms a protective layer in the air, offering good corrosion resistance.
- Highly efficient reducing agent, useful for deoxidation, dehydration, desulfurization, and decarbonization applications.
Applications
Calcium lumps are widely used in various industrial fields:
- Metallurgy: As a reducing agent in metallurgy, calcium is used to reduce metal oxides and acts as a deoxidizer and desulfurizer, widely applied in steel and ferrous alloy production.
- Alloy Manufacturing: Calcium is used as a deoxidizer in alloys, improving purity and stability.
- Petrochemical Industry: Calcium is used as a dehydrating agent in oils, helping remove moisture from oils.
- Electron Tube Manufacturing: Calcium is used in electron tubes as an absorbent to remove gases inside the tube, ensuring optimal performance.
