In the chemical and metallurgical industries, calcium carbide (CaC₂) remains a cornerstone raw material—especially in acetylene gas production, steelmaking, and organic synthesis. At Inner Mongolia Longwei Chemical Technology Co., Ltd., our high-purity carbonized calcium carbide meets international standards with ≤0.5% impurities, ensuring consistent performance and safety across global operations.
Before any operation, remember this rule: NO WATER CONTACT. Even trace moisture can trigger rapid exothermic reactions that release flammable acetylene gas. According to OSHA guidelines, over 70% of calcium carbide incidents stem from improper storage or handling—not equipment failure.
A lesser-known but critical risk is phosphine (PH₃) generation when using low-grade calcium carbide containing phosphorus impurities. In one documented case in India, a 500 kg batch of substandard CaC₂ released enough PH₃ to cause a minor explosion during water contact—resulting in $45,000 in damages and a 3-week plant shutdown.
Our product’s strict quality control ensures phosphorus content below 0.01%, far below the industry average of 0.05–0.1%. This isn’t just compliance—it’s operational peace of mind.
| Parameter | Industry Standard | Longwei Product |
|---|---|---|
| Purity (CaC₂%) | ≥85% | ≥98% |
| Moisture Content | ≤1.5% | ≤0.3% |
| Phosphorus Impurity | ≤0.1% | ≤0.01% |
A Mexican steel plant experienced frequent furnace downtime due to inconsistent acetylene purity from their previous supplier. After switching to Longwei’s high-grade CaC₂, they reported a 40% drop in maintenance calls and a 15% increase in yield within two months. The key? Stable reaction conditions and minimal side gases like PH₃ or H₂S.
Whether you're in mining, construction, or chemical manufacturing, understanding how to handle calcium carbide safely—and choosing the right grade—is no longer optional. It’s foundational to your operation’s efficiency and compliance.
