CRYOLITE

Properties of Cryolite

• Cryolite occurs in a monoclinic crystal state.
• The cryolite is whitish glassy in colour.
• The hardness of cryolite in the moh scale is 2.5 to 3.
• The specific gravity of cryolite is 2.95 to 3.
• Cryolite is transparent to translucent to transparent in nature due to which its refractive index is very low.
• Cryolite is invisible in nature, due to a similar refractive index.
• Cryolite as the essential component of the electrolyte (85 – 90 %) decreases the temperature of the smelting flux electrolysis.
