On June 12, 2021, the bulk carrier “ARAMIS” (Note: There is an inconsistency between the stated vessel name “SEASTAR EXPLORER CERTS” and the actual berthing vessel name “ARAMIS” in the original text, which has been organized based on the description) berthed at the port. A total of 2,000 tonnes of aluminum fluoride produced by HNNM underwent bag-cutting operations here and was successfully loaded onto the bulk carrier for shipment to overseas customers.
Company Profile
HNNM is a leading producer of aluminum fluoride with a total annual capacity of 280,000 tons.
Basic Product Information and Core Applications
Aluminum fluoride has a molecular formula of AlF₃ and a relative molecular mass of 83.98. It is a key chemical product with applications across multiple fields, whose core uses include:
Core additive in the aluminum electrolysis industry
It can lower the melting temperature of the electrolyte and improve its electrical conductivity, serving as an essential additive in primary aluminum production;
Metallurgy and material processing
Used as a flux in non-ferrous metal smelting, as well as a flux and component in ceramic glazes and enamel glazes;
Chemical and manufacturing fields
Acts as a side fermentation inhibitor in the production of essential oils and alcohol; serves as a welding flux in metal welding; and is also applicable in the manufacture of optical lenses, as a catalyst for organic synthesis, and as a raw material for artificial cryolite production.
Physical and Chemical Properties
Aluminum fluoride is a colorless triclinic crystal, appearing as white powder or large rhombohedral crystals. It has a density of 3.00 g/cm³, a melting point of 1040°C, and a boiling/sublimation point of 1272°C. It is slightly soluble in cold water, soluble in hot water, insoluble in most organic solvents, and shows high thermal stability. Hydrated forms include monohydrate, trihydrate, and nonahydrate.
