    Potassium fluoroborate is obtained by treating potassium carbonate with boric acid

     

    and hydrofluoric acid.

     

    B(OH)3 + 4 HF → HBF4 + 3 H2O

     

    2 HBF4 + K2CO3 → 2 KBF4 + H2CO3

     

     

    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.

     

    Markets & Applications
     

    Aluminium-metallurgy:
     

    - as component in fluxing and grain refining agents
     

    for aluminium and magnesium
     

    - as component in protecting salts for light metal castings
     

    Production of abrasives:
     

    - as active filler in reinbonded abrasives for metal treatment
     

    Production of soldering agents:
     

    - as component in fluxing agents for soldering and brazing

     

    According to one aspect of the invention, a braze composition is provided that

     

    comprises an aqueous binder system, a flux composition containing multiple

     

    inorganic compounds, and titanium hydride. The multiple inorganic compounds

     

    include potassium tetrafluoroaluminate and/or potassium tetrafluoroborate, more

     

    preferably both. The flux composition may contain additional inorganic compounds

     

    that, while optional, if used can be preferably selected to have a decomposition

     

    temperature or to form an intermediate complex having a decomposition

     

    temperature that is above or below the decomposition temperatures of potassium

     

    tetrafluoroaluminate and potassium tetrafluoroborate. According to a preferred

     

    aspect of the invention, the braze composition further contains a metallic braze

     

    alloy and is in the form of a braze paste or slurry suitable for use in manufacturing,

     

    coating, repair, and build-up of superalloy components


     

    Potassium tetrafluoroborate Properties:
     

    Whitegranule crystal,slightly dissolved in water,hot alcohol and ethanol,not

     

    dissolved in alkali solutions;deco
