Aluminum fluoride, whose molecules are composed of aluminum atoms and fluorine atoms. In 1 Molecular Of Aluminum Fluoride Atoms, aluminum atoms are combined with fluorine atoms according to a specific stoichiometric ratio.

Common aluminum fluoride, with the chemical formula $AlF_3 $. In this structure, one aluminum atom is combined with three fluorine atoms to maintain its stable structure by the force of ionic bonds. The aluminum atom loses three electrons, forming a cation with three positive charges ($Al ^ {3 + }$）； and the three fluorine atoms each acquire one electron, becoming a negatively charged anion ($F ^ - $）。 anions and cations attract each other to form a stable crystal structure.

This compound is used in many fields. In the metallurgical industry, it is often used as a flux, which can reduce the melting point, assist the smelting process of aluminum, and improve production efficiency. In the chemical industry, it also participates in many chemical reactions, serving as a catalyst or reaction raw material to promote the synthesis of specific compounds.
