ALUMINIUM FLUORIDE

Description:

Aluminum fluoride is the inorganic compound with the formula AlF3. It can be prepared by treating aluminum hydroxide or aluminum metal with HF. As a solid, its structure resembles that of rhenium trioxide, ReO3, consisting of distorted AlF6 octahedra. AlF3 is refractory, in strong contrast to the other halides of aluminum. AlCl3, AlBr3, and AlI3 are dimeric in the liquid and evaporate as dimers as well. In the gas phase, at ca. 1000 °C, aluminium fluoride exists as trigonal molecules of D3h symmetry group. The Al-F bond lengths are 163 pm. Aluminium fluoride is an important additive during electrolyte aluminium production because it lowers the melting point of the alumina feed and increases the electrolyte's conductivity. There is wide scope for new entrepreneurs to venture into this project.

Aluminium Fluoride

Description:

Aluminium fluoride is used in many industrial processes. It is one of the minor constituents added to the electrolytic cells during the production of metallic aluminium. It is also used in the preparation of white enamels, as an anti-reflection coating in complex optical systems, as a constituent in welding fluxes, and in the preparation of fluorine containing glasses, Aluminium fluoride (AlF3) is an inorganic compound used primarily in the production of aluminium. This colorless solid can be prepared synthetically but also occurs in nature. It is used in the production of aluminium metal. Uses Aluminium fluoride is primarily used in the production of aluminium. It is a critical additive to the molten electrolyte in aluminium metal production. Using today's technologies, it is impossible to manufacture aluminium without AIF3. Adding AIF3 allows the electrolytic process to take place at a temperature around 850°C, which is considerably lower than the melting point for aluminium oxide (Al2O3, mp ab. 1,500°C). As a result of its temperature-lowering properties, AlF3 has a definite energy saving effect. The industrial and use categories of AlF3 are IC8, UC40 and UC43. The main use of AlF3 is as a temperature-regulating agent, a pH-regulator and as a solubility enhancer of aluminium oxide in the electrolyte solution in the production process of aluminium. The use of AlF3 as such results in a lowering of the energy consumption in the aluminium pot. The raw material (aluminium oxide) is melted and split in aluminium and oxygen. The minor downstream uses of AlF3 are for metal treatment and for optical coating as an essential component of antireflective coatings and in semiconductors. A total of 52 tonnes of AlF3 was sold to traders, for which it is also assumed that it is used for other purposes than aluminium production. As no other significant uses were reported, neither by producers nor by downstream users, it is assumed that the main application is for production of aluminium, which is in general agreement with the information provided by the producers (> 99.6% used for aluminium production). As a consequence the risk assessment will focus on this particular use. Market Survey The Indian aluminium industry’s enthusiasm to grow smelting capacity on an ambitious scale here and abroad - the wanderlust is that of Nalco - was not dimmed in any way by the adverse performance of the metal during the recession. If all projects of Hindalco get commissioned on revised schedule, then it will see smelting capacity rising to 1.7 million tonnes from 500,000 tonnes and alumina refining capacity to 6.5 million tonnes from 1.7 million tonnes by 2013. Meanwhile, Novelis acquisition has given Hindalco global leadership in that value added segment where path breaking technologies are in application. Vedanta has arrived on the Indian aluminium scene much later than Hindalco and Nalco. While it has made up for the lost time by gaining control of Balco and Madras Aluminium, Vedanta is aggressively building new capacity through greenfield and brownfield routes. Aluminium fluoride (otherwise known as aluminum trifluoride) is a crystalline powder that is slightly soluble in water. It is mainly used in the production of aluminum metal. Aluminium Fluoride is able to decrease the melting point of electrolytes in the smelting process and improve the production efficiency. It is also utilized as a flux in welding applications; in the manufacture of ceramics and glass; in the making of aluminum silicates. The aluminium fluoride industry comprises a large number of players operating the world over. Lifosa AB, South Ural Cryolite Plant OJSC, Do-Fluoride Chemicals Co. Ltd. and S. B. Chemicals are amidst the most prominent manufacturers. The electrolytic bath in an aluminium electrolysis cell contains 80% synthetic cryolite (AlF3). Operating losses of fluorine from the cell are made up almost exclusively by the addition of further AlF3. The recent global economic crisis brought to the forefront and accelerated trends in the AlF3 market which have been evident for some time. It has become even more apparent that aluminium smelting should be carried out where the producer has access to energy sources which are abundant and relatively inexpensive. Similarly AlF3, which depends more on raw materials than energy, should be manufactured where the raw materials are abundantly available at a reasonable cost. It does not matter where the customers for aluminium or AlF3 are located but it does matter where the energy and raw materials are located.

Aluminium & Aluminium Products Budget 2013-14 Analysis Budget provisions. The following announcements have been proposed in the Union budget 2013-14 No change in the peak rate of basic customs duty of 10% for non-agricultural products. No change in the normal rate of excise duty of 12% and the normal rate of service tax of 12% Surcharge increased from 5% to 10% on domestic companies whose taxable income exceeds Rs 10 crore. In the case of foreign companies, who pay the higher rate of corporate tax, the surcharge will increase from 2% to 5%.

Aluminium Fluoride

Description:

Aluminium fluoride is the chemical compound with the formula AlF3. It has the consistency of a white powder. AlF3 is refractory, in strong contrast to the other halides of aluminium. Adding aluminium fluoride to the production process of primary aluminium lowers the consumption of electricity required in the smelting process and thereby considerably contributes to the reduction of production costs of aluminium. Energy is a major cost factor in aluminium production. Aluminium fluoride is not substitutable by other products in this respect.

 

Aluminium producers (smelters) are the main users of aluminium fluoride. For many years now the production of aluminium has been growing. Every year more than 20 million tons of aluminium is produced world-wide, some 30% of which in Europe. Depending on the type and efficiency of the production process, around 20 kg of aluminium fluoride are used in producing one ton of aluminium.

 

There are two main ways to produce aluminium fluoride. One production process is called the "dry process" in which aluminium fluoride is produced from fluorspar (CaF2) and results in a quality referred to as "high density" aluminium fluoride. High density quality consists of 90-92% of aluminium fluoride. The other main production process is called the "wet process" in which aluminium fluoride is produced from a by-product of fertilizer plants and results in a quality called "low density" aluminium fluoride. Low density quality consists of 97% of aluminium fluoride. All the producers that are addressees of this Decision produce and sell high density aluminium fluoride.

 

Aluminium fluoride is used in many industrial processes. It is one of the minor constituents added to the electrolytic cells during the production of metallic aluminium. Aluminium fluoride is used in turning alumina into aluminium. It lowers the melting point of alumina and boosts its electrical conductivity. Thus, due to demand it is a good project for entrepreneurs to invest.
