APPLICATIONS |
||
|
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 fluxin 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. |
