Function：
1. Hexafluorozirconic acid is highly corrosive and can react with metal surfaces.
2. In some chemical reactions, hexafluorozirconic acid can be used as a catalyst.
3. When hexafluorozirconic acid is in contact with the surface of metal or other materials, a protective film can be formed on the surface after proper treatment.
Application：
1. Hexafluorozirconic acid is used to remove the natural oxide film and oil on the surface of aluminum alloy, which is conducive to subsequent anodizing, painting and other processes.
2. As an additive to phosphating liquid, it can improve the quality of phosphating film.
3. Hexafluorozirconic acid can be used as a sintering aid for ceramic materials; It can also improve the mechanical and electrical properties of ceramic materials.
4. In the synthesis process of some organic compounds, hexafluorozirconic acid as an acidic catalyst can accelerate the reaction.
5. For the preparation of some electronic grade zirconium compounds, these compounds play an important role in the manufacture of electronic components (such as capacitors, piezoelectric ceramics, etc.).
