Size:
0.5-3mm
Product Advantages:
High gas yield, High purity, Stable performance, and Safety in use
Application
(1) The main raw material for producing acetylene gas.
(2) Cutting and welding for metal material
(3) To synthesize polyvinyl chloride (PVC)
(4) Fruit Catalyst
(5) The desulfurizer in steel industry
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.

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.
