Bonded Abrasives Cryolite | 13775-53-6

Cryolite is a mineral with the chemical formula Na3AlF6. It is a rare and naturally occurring compound that belongs to the class of halide minerals.

Chemical Composition:
Chemical Formula: Na3AlF6
Composition: Cryolite is composed of sodium (Na), aluminum (Al), and fluoride (F) ions.

Physical Properties:
Color: Usually colorless, but can also be found in shades of white, gray, or even pink.
Transparency: Transparent to translucent.
Crystal System: Cubic crystal system.
Luster: Vitreous (glassy) luster.
Bonded Abrasives Cryolite is crystalline white powder. Slightly soluble in water, density 2.95-3, melting point 1000℃ , easily absorbing water and become damp, decomposed by strong acids like sulfuric ACID and hydrochloride, then producing hydrofluoric acid and relevant aluminum salt and sodium salt.

1. Fused Alumina Production:
Cryolite is sometimes used as a flux in the production of fused alumina, an abrasive material. Fused alumina is produced by melting alumina (aluminum oxide) along with certain additives, including cryolite.

2. Bonding Agents:
In the manufacturing of bonded abrasives like grinding wheels, abrasive grains are bonded together using various materials. Cryolite might be used as part of the bonding agent formulation, especially in applications where a specific set of properties is required.

3. Grain Size Control:
Cryolite can influence the grain size and structure of abrasive materials during their formation. This can impact the cutting and grinding performance of the abrasive.

4. Grinding Applications:
Abrasive grains containing cryolite might be used in specific grinding applications where its properties, such as hardness and thermal conductivity, are advantageous.
