Islamic Azad University Produces Aluminium Fluoride to Aid Industry

Those working at the university in Khomein branch have managed to produce Aluminium fluoride, which reduces the melting point of Aluminium. This inorganic powder or granules (AlF₃) is colorless, and it has a density higher than that of water.

"In line with the development of Islamic Azad University, we are pursuing projects that not only contribute to scientific progress but also meet the vital needs of the country," said Mohammad Baqer Tavakkoli, the president of Islamic Azad University in Markazi province.

• Aluminium fluoride lowers Aluminium’s melting point, saving energy.
• Supports Aluminium, ceramics, metallurgy, and other industries.
• University also begins local production of phosphate fertilizer to cut imports.

It is mainly used during Aluminium production to act as a flux, which means the molten electrolyte gets warmer and can be transported better, needing less power despite high currents.

Apart from being used to make Aluminium, Aluminium fluoride is important in ceramics, metallurgy, and different industrial fields. In making Aluminium, the first process is refining the ore into pure Aluminium oxide, followed by carrying out electrolysis in a molten mixture of Aluminium fluoride and Cryolite.

"One of these projects is the production of Aluminium fluoride, which is a vital material for reducing the melting temperature of Aluminium. Also, the Islamic Azad University's Khomein branch, in cooperation with faculty members, has started producing phosphate fertiliser, most of which is supplied through imports, and domestic production can help the country's economy," added Tavakkoli.
