Potassium tetrafluoroaluminate is a white or light gray powder that is slightly soluble in water and highly acidic. At high temperatures, potassium tetrafluoroaluminate decomposes to release hydrogen fluoride gas. It is mainly used as a flux in the ceramic and glass industries, and also as a roasting agent in the aluminum smelting process to improve aluminum yield. In addition, it is also used as a catalyst in organic synthesis, for example for esterification, sulfonation and other reactions, and can be used as an etchant, cleaning agent, etching.

Uses of Potassium Tetrafluoroaluminate

1. Ceramics and glass industry: used as a flux to help reduce the sintering temperature and improve production efficiency.

2. Aluminum smelting: as a roasting agent to improve the yield and quality of aluminum.

3. Organic synthesis: as a catalyst, used in chemical reactions such as esterification and sulfonation, to promote the reaction rate and selectivity.

4. Etchants: Used to remove oxides or other coatings from metal surfaces for further processing or analysis.

5. Cleaning agent: used in industry to remove dirt and residue from metal surfaces.

6. Other industrial applications: May also be used in the production of abrasives, abrasives, and other industrial chemicals.
