Fluorine stone, commonly known as fluorspar, is a valuable mineral critical in numerous industrial sectors. With Dubai emerging as a strategic global trade hub, the demand for a reliable fluorine stone supplier is increasing rapidly. This article explores everything about fluorine stone—from its identity and uses to trade classifications and sourcing advantages in Dubai.
What Is Fluorine Stone?
Fluorine stone is the commercial term for fluorspar, a naturally occurring mineral composed primarily of calcium fluoride (CaF₂). It is the primary source of fluorine, a highly reactive element used across chemical, metallurgical, and ceramic industries.
Fluorine is rarely found in its elemental form due to its reactivity, so it is usually extracted from fluorine-containing minerals—especially fluorspar.
Other Names for Fluorine Stone
Fluorine stone is known by different names in various industries and regions, including:
Fluorspar
Calcium Fluoride
CaF₂ mineral
Fluorite (in gemology)
Acid-grade Fluorspar (when used in chemicals)
Metallurgical-grade Fluorspar (used in steel production)
Recognizing these names is important when sourcing from a fluorine stone supplier to ensure proper specifications are met.
Chemical and Physical Properties
Fluorine stone is appreciated not only for its composition but also for its distinct physical properties:
Chemical Formula: CaF₂
CAS Number: 7789-75-5
Molecular Weight: 78.07 g/mol
Appearance: Transparent or translucent crystals, often purple, green, or clear
Hardness (Mohs Scale): 4
Density: Approx. 3.18 g/cm³
Solubility: Insoluble in water
These properties make it ideal for industrial-grade applications that require chemical stability and high thermal resistance.
Applications and Industrial Usage
A trustworthy fluorine stone supplier provides high-purity fluorspar to cater to a wide range of applications:
Steel and Metallurgy: Used as a flux to remove impurities during smelting
Chemical Industry: Essential for producing hydrofluoric acid, which is a precursor to many fluorochemicals
Glass and Ceramics: Enhances the strength and clarity of specialty glass and enamels
Aluminum Production: Used in the production of aluminum fluoride and synthetic cryolite
Optics and Gemstones: High-grade fluorite is used in lenses due to its low dispersion properties
Toothpaste and Water Fluoridation: Trace fluorine is used for oral health, though in compound form
Fluorine Stone HS Code and CAS Number
For international trade, understanding the HS code and CAS number is essential for documentation and customs:
HS Code: 2529.22
CAS Code: 7789-75-5 (for Calcium Fluoride)
A professional fluorine stone supplier will always include these codes on invoices, packaging, and MSDS to ensure regulatory compliance.
Grades of Fluorine Stone
Fluorine stone is classified into different grades depending on its purity and usage:
Acid-Grade Fluorspar (≥97% CaF₂): Used in hydrofluoric acid production
Metallurgical-Grade (60–85% CaF₂): Used in steelmaking
Ceramic-Grade (85–95% CaF₂): Used in glass and ceramic manufacturing
Each grade serves a distinct industry, so it’s critical to partner with a supplier that provides reliable grade-specific analysis.
