Features:

Cryolite is a white crystalline powder with a density of 2.95 ~ 3.01g/cm3 and a melting point of about 1000°C. When the temperature is 18 ~ 100°C, the specific heat is 1.056J/j°C, slightly soluble in water, insoluble in anhydrous hydrogen fluoride; The content of crystal water decreases with the increase of molecular ratio, so the burning loss also decreases with the increase of molecular ratio.

Purpose:

Mainly used for electrolytic aluminum flux; It is also used for opalescent glass for enamel and sunshade and cosolvent for enamel production; Pesticides for crops; Flux for aluminum alloy casting; Ferroalloy and boiling steel production and resin rubber wear-resistant filler.

Packaging:

Products are made of laminated plastic woven or plastic woven bag, lined with plastic film bag packaging, each bag net weight 40kg, 50kg or 1000kg, product packaging according to commodity inspection or foreign requirements.
