China and India are the leading exporters of calcium carbide, accounting for the majority of global shipments, while Vietnam, Bangladesh, and Indonesia represent the largest importers in Asia. Calcium carbide prices have remained relatively stable amid steady demand from acetylene-based chemical manufacturing and steel desulfurization sectors. Export volumes from China have moderated slightly since 2023, while Indian exports have expanded, reflecting shifting regional production capacity and evolving calcium carbide prices.
Calcium carbide is a grayish-black, crystalline solid with a distinctive garlic-like odor when exposed to moisture; it is non-volatile, has a high melting point of approximately 2,300 °C, and decomposes before boiling. It is an inorganic compound classified as a metal carbide. Calcium carbide serves primarily as a precursor for acetylene gas generation via hydrolysis, and as a key raw material in the production of calcium cyanamide, vinyl chloride monomer, and various acetylenic chemicals. Its principal applications are in the synthesis of organic intermediates for plastics (e.g., PVC), synthetic rubber, solvents, and specialty chemicals used in metallurgy and steelmaking.
