0.5-3mm calcium carbide (CaC₂) is a granular form of calcium carbide, optimized for rapid acetylene gas generation. Compared to larger sizes like 25-50mm calcium carbide, our 0.5-3mm granules offer:
Faster reaction time – Smaller particles increase surface area, improving efficiency.
Higher gas yield – Produces 290-300L of acetylene per 1kg (vs. 270-280L for 5-15mm).
Easier handling – Ideal for portable acetylene generators and laboratory use.
We ensure >80% purity with low phosphine/sulfide content for safer operations.
Engineered for precise pneumatic injection and rapid kinetic chemical reaction. 100% Nitrogen-flushed hermetic packaging to eliminate oxidation and caking hazards.
Unlike large lumps that react gradually, 0.5–3mm granules offer a massive surface-area-to-mass ratio. This dimension is specifically manufactured for industrial applications where instant, complete chemical contact is required.
Ladle Furnace Desulfurization: Penetrates fluid steel slag rapidly, binding sulfur into CaS within seconds to maximize steel purity in Electric Arc Furnaces (EAF).
Controlled Gas Phase Synthesis: Provides precision-metered acetylene feed rates for organic intermediate production without temperature spikes.
Smooth Pneumatic Conveying: Uniformly screened to prevent nozzle clogging in automated injection lances.
| Technical Parameter | Standard Value | Buyer Benefit |
| Target Particle Size | 0.5 – 3.0 mm (≥ 90% in-range) | No oversized stones to jam injection lances |
| Guaranteed Gas Yield | ≥ 280 - 295 L/kg | High acetylene output optimized for metallurgical use |
| Fines Content (<0.5mm) | ≤ 5% strictly controlled | Drastically reduces dust explosion risks during handling |
| Phosphine (PH3) / Hydrogen Sulfide (H2S) | PH3 ≤ 0.08%, H2S ≤ 0.10% | Protects high-grade steel from re-contamination |
Fine carbide granules absorb ambient moisture exponentially faster than lumps. To guarantee 24-month shelf life without degradation, we employ a strict hazardous packing protocol:
Vacuum Nitrogen Purging: Every 50kg/100kg steel drum undergoes high-vacuum air extraction followed by a 99.9% pure dry nitrogen gas fill.
Heavy-Duty Moisture Liners: Internal high-density polyethylene (HDPE) barrier sealed with heavy-duty steel locking rings (UN 1402 Class 4.3 certified).

Precautions
Inspection upon Receipt
-Upon receipt of Calcium Carbide, check the barrels and pay attention to moisture protection (for example, snow and ice should be removed before storage).
-Check for signs of swelling, heat, or mechanical damage.
Handling Hot Drums
-If a drum is hot, do not cool it with water, and do not move the drum until it hascooled completely.
-The area should be cordoned off, and entry restricted until the drum cools.
Opening the Drum
-Use non-sparking tools (e.g,, brass hammer) to open the drum in a designatedarea.
-Ensure drums are opened only immediately before the calcium carbide is requiredfor use.
Personal ProtectiveEquipment
-Wear personal protective equipment (PpE), including gloves, helmets, and faceshields when opening drums and handling calcium carbide.
Transferring Calcium Carbide
- Use a charging skip or specialized transfer equipment, ensuring proper groundingduring transfer.
-All transfer tools should be equipped with gas-purging systems and anti-staticproperties.
Cleaning up Spillage
-Use natural fiber brooms and non-sparking tools to sweep up any spillage during transfer.
-Calcium carbide dust should be disposed of safely.
