Description

Calcium Silicide is an inorganic compound primarily used as a powerful deoxidizing and desulfurizing agent in metallurgy. Its high reactivity and ability to form stable silicates make it a critical material for controlling the composition and properties of various metal alloys. This product is essential for manufacturers in the steel, iron, and non-ferrous metals industries seeking to improve product quality and process efficiency.

Application

• Steelmaking Deoxidizer: Used to remove oxygen from molten steel, improving its strength and reducing porosity.
• Cast Iron Inoculant: Enhances the graphite structure in cast iron, leading to improved machinability and mechanical properties.
• Magnesium Production: Acts as a reducing agent in the Pidgeon process for the thermal production of magnesium metal.
• Pyrotechnics and Incendiary Devices: Utilized for its ability to produce intense heat and bright sparks upon ignition.
• Welding Rod Coatings: Incorporated as a component to stabilize the arc and improve weld metal quality.
• Specialty Alloy Production: Serves as a source of silicon in the manufacturing of certain ferroalloys and master alloys.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can degrade product performance. Store at room temperature (15-25°C).
