Whether in the steel industry for desulfurization, in welding technology for acetylene production, or in agriculture – calcium carbide is an indispensable raw material for professionals. However, its enormous reactivity requires expertise. Find out which parameters characterize pure calcium carbide, where it is specifically used, and how to handle and store the substance absolutely safely.

Technical Specification and Identification

For reproducible results in synthesis and industry, you need chemicals with clearly defined parameters. Our calcium carbide, BIOLABORATORIUM 1 kg, delivers exactly this reliability.

The basic identification data at a glance:

• Chemical formula: CaC₂
• CAS number: 75-20-7
• EC number: 200-848-3

Professional Application Areas at a Glance

Due to its unique chemical properties, calcium carbide covers a wide range of professional applications:

• Chemical Industry & Welding Technology: The most important application is the production of acetylene. When CaC₂ comes into contact with water, this highly flammable gas is produced. Acetylene serves as a central starting material for many chemical syntheses and is the preferred fuel gas in professional welding technology because it reaches extremely high flame temperatures.
• Steel Industry: Here, calcium carbide acts as a highly effective agent for desulfurization of steel. It reacts specifically with unwanted sulfur in the molten metal. The resulting calcium and sulfur compounds can be easily separated, which significantly improves the quality and mechanical strength of the steel.
• Agriculture: A less well-known but essential area of use is the acceleration of fruit ripening. The acetylene released from the carbide acts as an effective ripening gas that precisely prepares crops like bananas or mangoes for sale.
• Research and Development: In chemical laboratories, calcium carbide forms the basis for complex studies and experiments involving acetylene and its reaction pathways.

Strict Safety Regulations: The Reaction with Water

Calcium carbide allows no negligence in occupational safety. The most important hazard statement is H260: In contact with water releases flammable gases which may ignite spontaneously.

Absolutely observe these P-statements during handling to avoid accidents:

• P222: Do not allow contact with air.
• P231+P232: Handle under inert gas and keep absolutely dry.
• P370+P378: In case of fire, never use water! Use only sand or special dry extinguishing agents.

Recommended Storage Conditions for Maximum Safety

Correct storage not only ensures the quality of the product but also prevents life-threatening reactions in your facility.

Always store calcium carbide in a dry, well-ventilated place, far away from any moisture. Keep the original containers strictly closed, according to P422, and avoid locations with high temperatures or open sources of ignition. Proximity to other reactive chemical substances is also taboo. Always follow local safety regulations for hazardous materials.

Rely on the highest quality for your industrial and laboratory processes.
