Usage

General Description

Trisodium hexafluoroaluminate is a chemical compound with the formula Na3AlF6. It is a white, odorless, and water-soluble solid that is commonly used in industrial applications, particularly as a flux in aluminum smelting and refining processes. It is also used in the production of ceramics, glass, and other metal alloys. Trisodium hexafluoroaluminate is known for its ability to lower the melting point of metal oxides and improve their flow properties, making it a valuable tool in the manufacturing of various materials. Additionally, it has been studied for its potential use in water treatment and as a catalyst in organic synthesis. While trisodium hexafluoroaluminate is generally considered to be of low toxicity, exposure to high concentrations can cause irritation to the respiratory system and skin.
