ALUMINUM FLUORIDE TRIHYDRATE Usage And Synthesis

Chemical Properties

WHITE POWDER

Chemical Properties

Aluminum fluoride is a white, odorless powder or granule.

Uses

Aluminum fluoride trihydrate is used as an additive for the production of aluminum by electrolysis. It is also used to inhibit fermentation and in the preparation of low index films. It serves as a flux ingredient for the removal of magnesium in the refining of aluminum scrap. Further, it is used in the manufacture of aluminum silicates, ceramics and glass. In addition, it acts as a catalyst for organic synthesis and filler in glass industry.

Potential Exposure

Used as component of electrolyte from which aluminum metal is produced; in the manufacture of ceramics, enamels, aluminum silicate; as flux in metallurgy; as a fermentation inhibitor
