Foshan Shuangfu Chemical's Fluoroboric Acid (HBF4) is a strong, highly corrosive acid,

and its application includes:

1. As an electrolyte in electroplating and electroforming processes

Fluoroboric acid is used in metal plating and electroforming processes as an electrolyte.

It is particularly used in plating metals like copper, nickel, tin, and zinc on metal surfaces to

enhance corrosion resistance, alleviate wear and tear, and improve the appearance of metal coats.

2. In the synthesis of organic compounds

Fluoroboric acid is utilized in organic chemical synthesis as a catalyst, reagent, and solvent.

It is used to carry out reactions such as Friedel-Crafts acylation and alkylation, esterification, polymerization, and more.

3. As a component of electrolyte in lithium-ion batteries

Fluoroboric acid is added to electrolyte solutions used in lithium-ion batteries. It enhances the

solubility of lithium salt, thereby improving the lifespan and performance of batteries.

4. In etching semiconductor materials

Fluoroboric acid is a common etchant used to etch silicon and other semiconductor materials.

It plays a crucial role in the process used to manufacture semiconductor devices.

5. Cleaning and polishing metals

Fluoroboric acid is an effective agent used to clean and polish metal surfaces.

It can remove impurities, oxides, and residues, leaving the metal shining and looking new.
