Product Description

Product Description

Calcium Carbide

Calcium Carbide (CaC2) is an inorganic chemical with CAS No.75-20-7, EINECS No.200-848-3. It is a hard, brittle crystalline solid, grayish-white to black, available in lumps or powder. Its density is 2.22 g/cm³; insoluble in organic solvents. Reacts with water to produce acetylene gas and calcium hydroxide, classified as Class 4.3 dangerous goods. Industrial-grade purity: 80%-95%. Higher purity for chemical synthesis, standard for industrial use. Stable storage in dry conditions, easy transport in sealed, moisture-proof packaging.

As a key raw material, calcium carbide drives acetylene production across industries. Primarily, it generates acetylene gas, essential for welding and cutting in machinery, construction, and shipbuilding, known for high combustion temperatures and stable flames. In synthesis, acetylene is vital for PVC, vinyl acetate, polyvinyl alcohol, and acrylonitrile production, foundational for plastics, fibers, and adhesives.

In metallurgy, it serves as a desulfurizer and decarburizer, enhancing metal purity and properties. It produces calcium cyanamide, a nitrogen fertilizer and raw material for fine chemicals. It is used in industrial explosives for mining and as a reducing agent in rare metal smelting. Its diverse properties make it essential in chemical manufacturing, metallurgy, construction, and agriculture worldwide.
