Steadfast Supply: 2–120mm Calcium Carbide for Industrial Excellence

As a trusted partner in industrial chemistry, we deliver steadfast supply​ of calcium carbide (CaC₂)​ across the full spectrum of industrial sizes-2mm to 120mm-tailored to meet the diverse demands of acetylene production, steelmaking, chemical manufacturing, and beyond. Our commitment to quality consistency, reliable logistics, and customizable solutions​ ensures your operations run smoothly, whether you need fine granules for portable generators or oversized lumps for mega chemical reactors.

1. Full-Size Range: 2–120mm Calcium Carbide for Every Application​

We offer calcium carbide in 10+ standardized sizes​ within the 2–120mm range, each engineered for specific industrial needs:

Size Range​	Form​	Primary Applications​	Key Benefits​
2–5mm​	Fine Powder	Laboratory acetylene generation, small-scale chemical synthesis	Rapid reaction; precise dosing.
5–10mm​	Micro-Granules	Portable acetylene generators, hobbyist welding	Compact; fast gas evolution.
10–25mm​	Granules	Medium-scale acetylene plants, steel mill additives	Balanced reactivity; easy to handle.
25–50mm​	Lumps	Large acetylene generators, welding shops	Steady gas flow; minimal fines.
50–80mm​	Large Lumps	Chemical plants (PVC/rubber), heavy-duty welding	Slow, sustained output; durable for bulk use.
80–120mm​	Oversized Lumps	Mega steel mills, PVC factories	Ultra-slow reaction; minimal handling waste.

2. Quality Assurance: Industrial-Grade Purity & Performance​

Every batch of our calcium carbide meets ISO 9001 standards​ and is tested for:

High Purity: ≥93% CaC₂ (industrial grade) / ≥96% (high-purity grade).

Superior Gas Yield: ≥295 L/Kg (standard) / ≥305 L/Kg (high-purity).

Low Impurities: Sulfur ≤0.2%, phosphorus ≤0.15%, moisture ≤0.5%.

3. Steadfast Supply: Reliable Sourcing for Uninterrupted Operations​

As a vertically integrated manufacturer, we ensure:

Stable Production: 24/7 factory operations with a monthly capacity of 10,000+ tons.

Inventory Buffer: Stockpiles of all sizes to fulfill urgent orders within 48 hours.

Global Logistics: Partnerships with top shipping lines for fast delivery to major ports (Shanghai, Rotterdam, Houston).

4. Industrial Applications: Where Size Matters​

4.1 Acetylene Production​

Fine Sizes (2–10mm): Power portable generators for field welding and emergency lighting.

Medium/Large Sizes (25–120mm): Feed industrial reactors for PVC, synthetic rubber, and acetic acid.

4.2 Steelmaking​

Granules (10–25mm): Add to electric arc furnaces for efficient deoxidization.

Oversized Lumps (80–120mm): Use in basic oxygen furnaces for slow, uniform desulfurization.

4.3 Chemical & Advanced Materials​

High-Purity Grades: Produce silicon carbide (SiC) for semiconductors and specialty ceramics.

5. Custom Solutions & Packaging​

Tailored Sizes: Customize size ranges (e.g., 30–60mm) to match your reactor specifications.

Flexible Packaging: 50kg steel drums, 1-ton bulk bags, or loose cargo for bulk orders.
