Introduction

Calcium carbide (CAS: 75-20-7) is a grayish-brown solid in lump form. As an important chemical raw material, it reacts with water to produce acetylene gas, and is commonly applied in chemical synthesis, welding and cutting, the synthesis of calcium cyanide, and metal smelting.

Application

Acetylene Production & Use: Reacts with water to produce acetylene gas for chemical processes, welding, and cutting.

Chemical Feedstock: Raw material for solvents, specialty monomers, and pharmaceuticals.

Calcium Cyanamide Production: Used as an intermediate in the manufacture of fertilizers and nitrogen sources.

Metallurgy: Used as a reducing or carburizing agent in steelmaking.

Carbon Products: Produces carbon black and porous carbons for electrodes and adsorbents.
