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.

Synthesis

The concentration of 40% aluminum hydroxide slurry according to the reaction ratio added to the reaction kettle containing a concentration of 60% ammonium hydrogen fluoride solution for the reaction, charging time of 25 minutes, the reaction temperature is controlled at 100 ?? C, the reaction generates aluminum fluoride solution, ammonia is absorbed to get ammonia, the aluminum fluoride solution is crystallized, the crystallization temperature is 80 ?? C, the crystallization time is 5 hours, the crystallization of aluminum fluoride trihydrate.

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
