Calcium Fluoride (Fluorspar) (CaF₂)

Calcium fluoride (CaF₂) is a white insoluble solid. It occurs as the mineral fluorite (also called fluorspar). In pure form, it is colorless and transparent or translucent with a glassy luster and has a significant phenomenon of fluorescence.

Specialty Grades Available: Various screen mesh sizes down to superfine powder (45 microns)
Typical Chemical Properties

Metallurgical Grade (Metspar)
CaF₂ is composed of 51.1% calcium and 48.9% fluorine. Metspar is about 60%-85% calcium fluoride depending on where it is sourced and what residual elements are in the deposits.

Acid Grade (Acidspar)
Acid Grade Fluorspar or acidspar (CaF₂), is a fine-grained material composed of 51.1% calcium and 48.9% fluorine. Acidspar is generally 97% – 99.9% calcium fluoride depending on the deposits, mining techniques, and processing techniques.

Typical Applications

Calcium fluoride is used as the source of fluorine and the material to make hydrofluoric acid. It is used in iron and steel smelting as a fluxing agent in ferrous metallurgy. It is used to manufacture specialty lenses, glass, enamel, and glaze and is used in fluorescent lamps. It has dental applications. Other uses are in fiberglass production, ceramics, and welding rod coatings.

Packaging Options

Jars, pails, drums, multi-ply paper bags, and bulk bags

Classification

Calcium Fluoride TSCA (SARA Title III) Status: Listed. For further information, please call the EPA Office of Chemical Safety and Pollution Prevention (OCSPP) at 202-564-2902. Calcium Fluoride CAS Number: 12057-24-8 Calcium Fluoride European Community Number: 232-188-7 (Listing) U.S. National Library of Medicine (NIH): Substance Listing. Safety Data Sheet: Contact READE for the latest SDS Moderately toxic by intraperitoneal route. Mildly toxic by ingestion. The hazards of calcium fluoride are due primarily to the harmful effects of the fluorine content and its silica content.
