Fluoroboric acid and the fluoroborates are commercially important to a variety of industries. The acid is used in plating circuits, in metal finishing, in the production of aluminum, and as an acid catalyst. Main group metal and ammonium fluoroborates find use as fluxes, as catalysts, and in flame-retardant manufacture. Transition- and other heavy-metal fluoroborate salts are used in the plating industry and as catalysts. Properties and manufacture are described.

Acid Fluoborate Copper Processes Copper fluoborate is much more soluble than copper sulfate. Therefore for high-current-density and high-speed processes, the copper-ion concentration can be more than double that obtainable in the sulfate baths. The fluoborate ion also helps provide solubility and conductivity. But when compared with sulfate baths, the fluoborate bath has less throwing power. The copper sulfate bath is more widely used than the fluoborate because it is less expensive. Also, many more additive systems have been developed for copper-sulfate formulations. Copper fluoborate baths are more hazardous to use and harder to waste treat than sulfate baths. And as with the sulfate baths, the fluoborate solutions are very corrosive, making careful design of plating equipment important. Chemistry of copper fluoborate baths. Table VII shows the composition of a typical acid copper fluoborate bath. If the fluoboric acid concentration is too low (pH above 1.7), the deposit may be dull, dark, and brittle. Add boric acid to stabilize the bath and to prevent the decomposition of the fluoborate to fluoride. The anode film and its care in a fluoborate bath are very similar to the requirements described for the copper sulfate bath

Local: Fluoroboric acid is used in plating circuits; metal finishing; electropolishing of aluminium and its alloy; component of galvanic baths; organic synthesis as catalyst for alkylations and polymerisation; stabilisation of diazo salts; manufacturing of inorganic fluoroborate salts.

Inorganic fluoroborate salts are used as components of fluxing and plating, as catalysts, in flame-retardant manufacture, in metal treatment; grain refining agents; as active fillers in resin bonded abrasives; in electrolytic generation of boron, preparation of glazing frits.
