Cryolite is a chemical with the molecular formula na3alf6. Cryolite is white crystalline powder, sand, and granular, and also has light red powder, sand, and granular, with a specific gravity of 2.95-3.01g / cm3, a melting point of about 1000 ° C, and a specific heat of 18-100 ° C. 1.056J / g ℃, slightly soluble in water, insoluble in anhydrous hydrogen fluoride; the content of crystalline water decreases with the increase of the molecular ratio, so the burning loss decreases with the increase of the molecular ratio. Different molecular ratios After removing the attached water, the burning loss of the ointment at 800 ° C was 10.34% at a molecular ratio of 1.74, 6.22 at a molecular ratio of 2.14, 6.22 at a molecular ratio of 2.14, and 2.56% at a molecular ratio of 2.63.
Cryolite meaning determines the widespread use of cryolite, and cryolite meaning also determines the irreplaceable behavior of cryolite, so cryolite is an important and indispensable blood in industry.
Cryolite is mainly used as a flux for aluminum electrolysis. It is suitable for electrolytic aluminum tank opening and normal production, adjusting the electrolyte molecular ratio level. Cryolite is also used as opacifying agent in glass and opacifiers and co-solvents for enamel production; pesticides for crops; fluxes for casting aluminum alloys, production of ferroalloys and boiling steels And resin rubber wear-resistant fillers. Our company can supply cryolite with high molecular ratio, medium molecular ratio and low molecular ratio. The specifications are powdery / sandy.
