Aluminium oxide is a white, amphoteric metal oxide with chemical formula alpha-Al2O3. It is an abrasive that is used in the production of various chemicals and other applications.
In the chemical field, aluminum oxide is used in the production of dental cements, refractory materials, and many other products. It is also an abrasive and electrical insulator. However, it can cause irritation to the upper respiratory tract and central nervous system.
Aluminum oxide is an acidic material that can react with sodium hydroxide, nitric acid, and calcium hydroxide. It also has a conjugate base in the form of HCl.
It is used in the chemical industry as a catalyst in a number of reactions. For example, aluminium chloride is formed by the reaction of hydrochloric acid with a dilute solution of aluminium oxide.
The American Conference Government Industrial Hygienists released a document on the exposure of aluminum oxide to humans. It included 29 data points.
The exposure of corundum workers to finely divided aluminium powders was reported to lead to pneumoconiosis and dyspnea. Diffuse irregular lace-like granular shadows were observed in the respiratory mucosa of these workers.
This chemical is used as a catalyst in the synthesis of organic compounds. It is also a catalyst in the initiation of alkylation reactions.
The American Conference Government Industrial Hygienists documented aluminum oxide exposure values for two different groups. Both the powder and fume groups had a high rate of clearance after a day.
