What is Calcium Metal Granular and application ?

What is Calcium Metal Granular?

Calcium metal granular is a form of calcium (Ca) that is produced in small, granulated particles. It is metallic in nature and is typically supplied in various granule sizes depending on its application. The material is highly reactive, especially in the presence of water or air, and it is stored under protective conditions to prevent unwanted reactions.

Key Characteristics:

• Purity: The purity of calcium metal granules can vary, but high-purity forms are often used for industrial applications.
• Size: Granules are usually small, ranging from fractions of millimeters (like 0.2mm) to several millimeters (up to 2mm or more).
• Reactivity: Calcium metal is highly reactive with water, releasing hydrogen gas, and must be handled carefully.
• Density: Calcium is lightweight, with a density of approximately 1.54 g/cm³.

Applications of Calcium Metal Granular:

1. Deoxidizer in Steelmaking:
2. Alloying Agent in Non-Ferrous Metals:
3. Purifying Agent in Metallurgical Processes:
4. Reducing Agent:
5. Desulfurizer:
6. Electronics and Chemical Industry:
7. Calcium in the Refining of Rare Earth Elements:

Storage and Handling:

• Storage: Due to its high reactivity with moisture and air, calcium metal granules must be stored in airtight containers, typically in inert atmospheres such as argon or under dry mineral oil to prevent reactions with water.
• Handling: Proper care and safety precautions, such as wearing protective equipment, must be taken when handling calcium metal to avoid reactions with air or moisture, which can be hazardous.

Calcium metal granular plays a crucial role in the metallurgy and steel industries as a deoxidizer, desulfurizer, and alloying agent. Its use improves the quality and performance of various metals and alloys, especially in steelmaking, aluminum production, and the refining of rare earth elements. Its highly reactive nature requires careful storage and handling, but it remains indispensable in these industries.
