Fluorosilic acid itself can be easily obtained from fertilizer products and phosporic acid production. The highest occupied molecular orbital (HOMO) for aluminum and fluoride is a p orbital, this means that it is filled when there are eight electrons in it. Aluminium fluoride or also known as Aluminium trifluoride is an inorganic compound with the formula of AlF3.xH2O. All other trademarks and copyrights are the property of their respective owners. For a small laboratory scale, alumina trihydrate or aluminium hydroxide (Al(OH)3) is mixed with hydrofluoric acid (HF) to produce aluminium fluoride. Aluminium fluoride is a white crystal/powder, which sublimes at 1272 degree celcius. Aluminium fluoride plays a great role in ceramic production as it is the main chemical compound used in glazes for finished products. One of the aluminium compound is being extracted from aluminium oxide using electric current or electrolysis through the melted compound. This means that each molecule of aluminum fluoride can form weak bonds with either one or three molecules of water. This method is commonly used in the industry due to the cost is the lowest compared to the other two methods before. It occurs naturally as oskarssonite and rosenbergite. Aluminium fluoride or also known as Aluminium trifluoride is an inorganic compound with the formula of AlF 3.xH 2 O.
