High Gas Yield Calcium Carbide CaC2 15-25mm
Products Description
Calcium Carbide, also known as CaC2, is an industrial chemical material mainly used for acetylene gas generation. When used under controlled industrial conditions, calcium carbide reacts with water to produce acetylene gas, which is widely used in welding, cutting, chemical synthesis and industrial gas production.
For acetylene producers, Calcium Carbide CaC2 15–25mm is a practical particle size because it offers a balance between reaction speed and feeding stability. Very small particles may react too quickly or increase dust loss, while oversized lumps may react more slowly. The 15–25mm size is commonly selected when buyers need stable gas output and easier handling in industrial acetylene systems.
For calcium carbide buyers, the key quality indicator is not only appearance or CaC2 content. Gas yield, particle size distribution, dust ratio, moisture control, drum sealing and safe transportation all affect the real value of the material.

For acetylene production, buyers should pay special attention to gas yield and moisture control. A high-yield calcium carbide batch can improve acetylene output, but poor storage or moisture exposure may reduce practical performance and create safety risks.
Applications of Calcium Carbide CaC2 15–25mm
Acetylene Gas Generation
The main use of Calcium Carbide CaC2 15–25mm is industrial acetylene generation. This size is suitable for acetylene gas plants and continuous gas supply systems that require stable output and controlled reaction behavior.
Welding and Cutting Gas Supply
Acetylene generated from calcium carbide is widely used in welding and metal cutting supply chains. For this application, stable gas yield and sealed storage are important.
Chemical Synthesis
Calcium carbide can serve as a raw material in acetylene-based chemical processes. Buyers should select the suitable grade and size according to their process requirements.
Metallurgical Use
Calcium carbide may also be used in selected metallurgical applications such as desulfurization, depending on the process. For this use, particle size and reaction control should be confirmed before ordering.
acking, Storage and Transportation
Calcium carbide is moisture-sensitive and must be packed carefully. Contact with water or humidity can affect product quality and generate acetylene gas. For this reason, sealed steel drum packing is strongly recommended for export shipments.
Common packing options include:
| Packing Type | Suitable Use |
|---|---|
| 50kg steel drums | Standard industrial use and easier handling |
| 100kg steel drums | Common export packing |
| 250kg steel drums | Bulk industrial buyers |
| Palletized drums | Easier warehouse handling |
| Customized packing | Based on buyer requirement and local regulations |
For long-distance transportation, drums should remain sealed, dry and clearly labeled. Buyers should confirm local dangerous goods import requirements before shipment. EIGA guidance also emphasizes strong containers and air-tight, water-tight closure for calcium carbide packaging.

FAQ
Q:What is Calcium Carbide CaC2 15–25mm used for?
A:Calcium Carbide CaC2 15–25mm is mainly used for industrial acetylene generation. It can also be used in selected chemical and metallurgical applications under proper industrial conditions.
Q:Why is gas yield important for calcium carbide?
A:Gas yield shows how much acetylene can be generated from calcium carbide. A higher and more stable gas yield helps improve acetylene output and raw material efficiency.
Q:What gas yield is common for 15–25mm calcium carbide?
A:Commercial 15–25mm calcium carbide is commonly supplied with gas yield around ≥285 L/kg or ≥290 L/kg, depending on grade and batch. Final values should be confirmed by batch COA.
Q:Why choose 15–25mm instead of smaller calcium carbide?
A:15–25mm calcium carbide offers a balance between reaction speed and handling stability. It has lower dust risk than very fine particles and more responsive reaction behavior than oversized lumps.
Q:How should calcium carbide be packed?
A:Calcium carbide should be packed in sealed, moisture-resistant steel drums, commonly 50kg, 100kg or 250kg. It must be protected from water and humidity during storage and transportation.
Q:Can Zhen An provide COA and MSDS?
A:Yes. Zhen An can provide batch COA and MSDS for Calcium Carbide CaC2 15–25mm. Third-party inspection can also be arranged before shipment if required.
