Used in industrial cleaning agents and metal surface treatment processes due to its strong anionic reactivity and ability to remove oxides. The fluorine and chlorine components enhance etching and passivation in semiconductor manufacturing and aluminum processing. Nitrate and nitrite contribute to corrosion inhibition in cooling systems and metalworking fluids. Sulfate acts as a stabilizing agent in electroplating baths and helps maintain ionic balance in large-scale water treatment systems. Commonly applied in combination for decontamination in oil and gas pipelines and in formulation of specialty detergents for precision cleaning.
