Calcium Carbide: Industrial-Grade Chemical for Reliable Applications
Calcium Carbide (CaC₂) is a versatile and highly reactive compound widely used across industries ranging from metalworking to gas production. Known for its distinctive grey appearance and sharp odor (from acetylene gas release upon contact with moisture), Calcium Carbide remains a cornerstone in manufacturing, construction, and chemical processing worldwide.
At City Chemicals EU, we supply high-quality Calcium Carbide that meets strict international standards, ensuring safety, consistency, and maximum performance for industrial clients.
What is Calcium Carbide?
Calcium Carbide is a crystalline substance produced by heating a mixture of lime and coke in an electric arc furnace at very high temperatures. When it reacts with water, it produces acetylene gas (C₂H₂), a flammable compound used extensively in welding, cutting, and other industrial processes.
The solid by-product of this reaction is calcium hydroxide, which also has practical applications in construction and agriculture.
How Calcium Carbide Works
The effectiveness of Calcium Carbide lies in its ability to rapidly release acetylene gas upon hydrolysis. This reaction provides a clean, high-temperature flame, making it a preferred choice for metal cutting and welding operations. In addition, acetylene generated from Calcium Carbide is utilized in chemical synthesis, producing solvents, plastics, and synthetic rubbers.
Key Benefits
-
Reliable Gas Generation: Produces acetylene gas on demand, ensuring controlled and consistent supply.
-
Versatile Applications: Used in welding, construction, mining, steel production, and chemical synthesis.
-
Cost-Effective: An economical source of acetylene compared to compressed gas cylinders.
-
Longevity: Properly stored Calcium Carbide maintains reactivity for extended periods.
-
Global Industrial Standard: Recognized as a reliable compound across multiple industries.
Safety and Handling
While Calcium Carbide is a highly useful chemical, it must be handled responsibly. The reaction with water is vigorous, so exposure to moisture should be avoided until use. Storage requires dry, airtight containers to prevent premature reactions. Operators should wear protective equipment, including gloves and eye protection, to ensure safe handling.
Shelf Life and Storage
When stored under dry, airtight conditions, Calcium Carbide can maintain its stability for up to 12 months. For maximum safety and efficiency, it should be kept away from water sources and stored in a cool, ventilated environment.
Applications and Usage Areas
-
Metal Industry: Gas welding and cutting.
-
Construction: Concrete dehumidification and hardening.
-
Mining: Illumination in carbide lamps (historical and niche use).
-
Chemical Manufacturing: Production of acetylene, vinyl chloride, and other organic compounds.
-
Agriculture: Controlled ripening of fruits (regulated use).
