China and India are the leading exporters of calcium sulfide, accounting for the majority of global shipments, while the United States, Germany, and South Korea represent the largest importers. Calcium sulfide prices have remained relatively stable amid steady cross-border flows, with no major disruptions in supply chains observed in recent trade data. Exports from China have slightly increased year-on-year, while Indian exports have plateaued, suggesting a consolidation of China’s position as the dominant supplier in the global calcium sulfide market.
Calcium sulfide is a white to yellowish crystalline solid, typically odorless and non-volatile, with a high melting point of approximately 2,525 °C. It is an inorganic ionic compound classified as a metal sulfide. Calcium sulfide serves primarily as a precursor in the production of phosphors—especially for cathode-ray tube (CRT) screens and electroluminescent devices—and as a reducing agent in metallurgical processes. It is also employed in the synthesis of other sulfur-containing compounds and in certain pigment formulations. Typical application areas include electronic materials, specialty ceramics, and niche applications in luminescent coatings and optical materials.
CALCIUM SULFIDE is used in electron emitters. Luminous CaS used for making luminous paints or varnishes.
CALCIUM SULFIDE is OFF-WHITE POWDER
