Fluorides; of aluminium

HS v2022 Code: 282612

About fluorides; of aluminium

HS code 282612 covers the classification of fluorides of aluminium, an important group of inorganic compounds with a wide range of industrial applications. Aluminium fluorides are essential raw materials for the production of aluminium metal, as well as being used in the manufacture of various other chemicals, ceramics, and specialty glass products. This industry plays a crucial role in supporting the global aluminium industry, which is a key component of the broader metals and mining sector.

Production process

Aluminium fluorides are typically produced through the reaction of aluminium oxide (Al2O3) with hydrofluoric acid (HF). This process involves dissolving aluminium oxide in the acid, followed by evaporation and crystallization to obtain the desired aluminium fluoride compound. The specific production techniques may vary depending on the purity and grade of the final product required.

Production inputs

The main inputs for the production of aluminium fluorides include aluminium oxide, hydrofluoric acid, and various energy sources (such as electricity or natural gas) to power the manufacturing process. Specialized equipment, such as reactors, evaporators, and crystallizers, are also essential for the efficient production of these compounds.

Production outputs

The primary output of HS code 282612 is aluminium fluoride, which is then consumed by various downstream industries. These include the 760110 aluminium smelting industry, where aluminium fluoride is used as a flux to lower the melting point of the aluminium electrolyte. Aluminium fluorides are also used in the production of 320611 ceramic pigments and enamels, 281810 aluminium oxide, and 283329 other inorganic fluorides.
