Buy good quality CALCIUM METAL LUMP high purity at Wedge India. Calcium metal in lump form is often used in industrial applications where larger quantities of the metal are needed. The lumps provide a convenient form for handling, storage, and use in various metallurgical processes.
 
Characteristics
• Form: Calcium metal is available in various sizes of lumps, typically ranging from a few millimeters to several centimeters in diameter.
• Appearance: Silvery-white with a metallic luster, but it can appear dull due to the formation of a grayish oxide layer when exposed to air.
• Purity: Typically high purity, often above 99%, to ensure effectiveness in industrial applications.
 
Production
• Electrolytic Process: Produced by the electrolysis of molten calcium chloride, which results in high-purity calcium metal that can be cast into lump form.
• Reduction Process: In some cases, calcium can be produced by reducing calcium oxide with aluminum at high temperatures, forming calcium metal that is then processed into lumps.
 
Applications
1. Metallurgical Industry:
• Deoxidizing and Desulfurizing Agent: Calcium metal lumps are used in the steel industry to remove oxygen and sulfur impurities, leading to improved steel quality.
• Alloy Production: Used in the production of certain alloys, such as aluminum-calcium and magnesium-calcium, which are used for their specific mechanical properties.
2. Reduction of Metal Oxides:
• Calcium lumps are employed as reducing agents in the extraction of certain metals from their oxides, such as thorium and uranium, converting them to their metallic forms.
3. Lead-Calcium Batteries:
• Used in the production of lead-calcium alloys for battery grids, offering advantages such as better mechanical strength and reduced water loss compared to traditional lead-acid batteries.
4. Chemical Industry:
• Calcium Compounds: Calcium metal lumps are used to produce various calcium compounds like calcium carbide, which is used in the production of acetylene gas.
 
Handling and Storage
• Storage: Calcium metal lumps should be stored in airtight containers or under an inert atmosphere to prevent oxidation and reaction with moisture.
• Handling: Due to its reactivity, proper protective equipment should be used to prevent skin contact and inhalation of dust when handling calcium metal lumps.
• Safety Precautions: Calcium should be kept away from water and acids, as it reacts vigorously to produce hydrogen gas, which can be hazardous.
