China is the dominant global exporter of calcium fluoride, accounting for the majority of international shipments, while the United States, Germany, and Japan are the largest importers. Calcium fluoride prices have remained relatively stable amid consistent demand from fluorine chemical and metallurgical sectors. Exports from South Africa and Mexico have shown modest growth since 2022, signaling emerging supply diversification alongside sustained Chinese dominance.
Calcium fluoride is a white, crystalline solid that is odorless and non-volatile, with a high melting point of approximately 1,418 °C and negligible solubility in water. It is an inorganic ionic compound, classified as a metal halide and the calcium salt of hydrofluoric acid. Industrially, it serves primarily as a raw material for the production of hydrogen fluoride (HF) via reaction with sulfuric acid—a key step in manufacturing fluorinated chemicals, aluminum fluoride, and synthetic cryolite. Its principal applications are in metallurgy (as a flux in aluminum and steel production), optical-grade components (e.g., lenses and windows for UV and IR spectroscopy), and ceramics. It is also used in the manufacture of opalescent glass and enamels.
Main primary source of fluorine & its compd, in ferrous metallurgy as flux to incr fluidity of slag, synthetic fluorspar is used in optical industry (transmits uv rays), pure form used as catalyst in dehydration & dehydrogenations, used to fluoridate drinking water.
This chemical is included in Basic Chemicals - Fluorochemicals. See more about what is Calcium fluoride and Calcium fluoride SDS information.
