As a professional calcium carbide manufacturer with over 15 years of production experience, our factory specializes in producing high-quality 1-7mm calcium carbide stone. This particle size is especially suitable for acetylene generation, steel desulfurization, and various chemical synthesis processes. When you buy calcium carbide stone from our factory, you get consistent quality and performance backed by strict production controls.

Outstanding Gas Yield (L/kg)

Our 1-7mm calcium carbide stone offers excellent acetylene gas yield. Standard grade achieves ≥295 L/kg, while premium grade reaches ≥305 L/kg (under 20°C, 760mmHg). The uniform particle size distribution — 80% within 1-7mm the gas yield can reach ≥245L/kg— ensures stable, efficient reaction rates. Every batch is lab-tested before shipment. If you need reliable gas generation, buy calcium carbide stone from a source that guarantees accurate dosing and high yield.

Professional Packaging Solutions

We understand packaging is critical for safety and storage. Standard options:

• 100kg/50kg new steel drums with nitrogen sealing--22.5 tons per 20'FCL 

• 250kg drum steel drums for bulk use--20tons per 20'FCL 

All drums meet UN hazardous material transport standards. Labels include batch number, net weight, gross weight and gas yield data.

Customizable Packaging Available

Need special packaging? Our factory offers customizable options:

• Branded color printing on drums

• Different drum sizes (50kg, 100kg, 250kg)

• Heat-shrink pallet covers for warehouse stacking

Tell us your requirements, and we will tailor the packaging accordingly. This flexibility is another reason customers consistently buy calcium carbide stone from us rather than switching suppliers.
