Material Overview
Fluorite, also known as fluorspar, is a mineral that comes in a wide range of colors and has many uses. At CK-Mining, we offer high-quality fluorite specimens for collectors as well as industrial quantities for processing and manufacturing.
Fluorite is composed of calcium fluoride (CaF2) and can appear purple, blue, green, yellow, colorless, or multicolored. It has a glassy luster and is often transparent or translucent.
Major deposits are found in China, Mexico, England, and the United States, and the mineral can form when hot fluids circulate through rock during the cooling of magma or lava.
Applications
- Flux input in steel and aluminum production to lower the melting point of raw materials.
- Feedstock for hydrofluoric acid used in refrigerants, gasoline additives, and electronics.
- Flux and fluoride source in glass, enamel, and ceramic production.
- Material for lenses, prisms, and windows in optical applications.
- Decorative stone and semiprecious material for lapidary work.
Additional Notes
- Fluorite is fluorescent under ultraviolet light and can also exhibit piezoelectric and pyroelectric behavior in specialized applications.
