Hydrofluoric Acid 70% is mainly used in:
1. HF 70% is used in the glass industry for etching glass surfaces to create decorative patterns or markings.
2. HF 70% is used to etch silicon wafers to create microstructures and circuits.
3. Hydrofluoric acid 70% can be used to dissolve silica (silicon dioxide) and other minerals for chemical analysis.
4. HF 70% is used for cleaning and etching certain metals, particularly stainless steel and titanium, to prepare them for further processing or welding.
5. HF 70% is used in the oil refining industry for alkylation processes to produce high-octane gasoline.
6. HF 70% is used to extract minerals like fluorite and aluminum from their ores. It can also be used to refine certain rare earth elements.
7. Hydrofluoric acid 70% is used as a catalyst or reagent in some chemical reactions and syntheses.
8. HF 70% is used in the oil refining industry for alkylation processes to produce high-octane gasoline.
