Product Information
Cryolite (Sodium
fluoroaluminate) is a white crystalline powder or a sandy-size granularity, and
a pinkish crystalline powder or a sandy-size granularity as well.
Sp.gr.2.95—3.01g/cm3, melting point about 1000°C, specific heat 1.056j/g°C at
18—100°C.Cryolite’s slightly soluble in water, but insoluble in
anhydrous hydrogen fluoride. The content of Cryolite’s crystal
water will be decreased while the increasing of the molecular ratio, therefore
its loss on ignition will be also decreased while the increasing of the
molecular ratio. After the paste of synthetic cryolite with
different molecular ratio dehydrates, the loss on ignition at 800℃ will
appear 10.34%, 6.22% and 2.56% when the molecular ratio reaches 1.74, 2.14 and
2.63 reactively.
Cryolite’s
application
Cryolite is
mainly used in flux of electrolytic aluminum, pesticide, flux of ceramic
colors, anti-rubbing filling agent of resin and rubber, electrolytic liquid for
production of iron alloy rimmed steel and furnish of emery wheel.

Size: sandy (80mesh), powder (200mesh, 325mesh), granule (0-10mm).
Cryolite’s
physical characteristic
Cryolite has
the characteristic of color is clear or white to yellowish, but can also be
black or purple; luster is vitreous; transparency crystals are transparent to
translucent; crystal system is monoclinic; crystal habits are usually massive
and as pseudo-cubic crystals, some with pseudo-octahedral truncations.
Other characteristics: index of refraction is 1.338 which is close to the index
of refraction of water. As a consequence, clearcryolite crystals or
powdered cryolite will nearly disappear in water. Also there
is no salty taste which is helpful in distinguishing cryolite from the mineral.
Packaging
of Cryolite
Cryolite can be packed in 25/50/1000kg plastic woven bags
with shrink film, or according to customer's requirements.
