    Description

     

    Potassium fluoroborate (KBF4) is usually used in aluminium-metallurgy, for the

     

    production of abrasives, soldering agents and ceramics, and in the chemical

     

    industry.

     

    Potassium fluoroborate is used in the the following 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 soldering agents:
       
    • as component in fluxing agents for soldering and brazing

    3. Applications

     

    Aluminium Industry

     
     
    Inorganic fluorine compounds play an outstanding role in the aluminum industry.
     
    They are frequently encountered not only in the manufacture, but also in the
     
    processing and finishing of aluminum.
     
    The manufacture of aluminum on a commercial scale was first made possible with
     
    the introduction of cryolite at the end of the 19th century. Cryolite as the essential
     
    component of the electrolyte (85 – 90 %) decreases the temperature of the smelting
     
    flux electrolysis.
     
    Other important additions to electrolytes in current commercial use are aluminum
     
    fluoride, calcium fluoride and lithium fluoride. These fluorides increase the
     
    conductivity of the electrolyte and improve the efficiency of the used energy. The
     
    aluminum so produced has a purity of between 99.5 and 99.9 %. Refining, that is to
     
    say the thorough cleaning and improvement of aluminum, is carried out for example
     
    by a process of three-layer fused-salt electrolysis. This method represents the only
     
    commercially viable process for the production of pure aluminum. Further
     
    electrolyte components from our product range which may be used are barium
     
    fluoride or calcium fluoride. Aluminum produced by this method has a purity of
     
    between 99.99 and 99.999 %.

     

    Casting Technology

     

    In the aluminum industry, salt covers are used as an aid in casting. The salt covers
     
    are a mixture of substances which protect molten aluminum alloys from oxidizing.
     
    The molten salt mixture also prevents gases from entering the bath, reduces heat
     
    losses from the surface of the molten metal
     
    and absorbs impurities which rise to the surface of the melt. Suitable salt covers are
     
    fluxes containing cryolite or sodium fluorosilicate. The melting points of these fluxes
     
    are reduced by the addition of, for instance, sodium chloride or potassium chloride
     
    to such an extent that they liquefy at
     
    the prevailing working temperatures.

     

    Surface Treatment

     

    Hydrofluoric acid and ammonium bifluoride are the bath constituents for the surface
     
    treatment of pure aluminum. Bright reflective surface on the aluminum is achieved
     
    by chemical polishing. Inorganic fluorides are also of critical importance in the flux
     
    brazing of aluminum and aluminum alloys, acting to remove the oxide layer.

    Abrasives Industry

     
    In recent decades there has been a steady increase in the quality of abrasives. This
     
    is especially true for elastically and fixed bonded abrasives, and is due in no small
     
    part to the use of abrasively active filler materials such as Solvay-Cryolite.
     
    Abrasively active fillers are today encountered in almost all high performance
     
    abrasives employed in the grinding of metals. Fixed bonded abrasives are abrasive
     
    bodies which are produced in a wide variety of forms. Examples of abrasives held
     
    on substrates are abrasive papers (generally without abrasively active filler
     
    materials), abrasive belts and abrasive fibers. Aluminum oxide and silicon carbide,
     
    produced by fusion processes in electric furnaces, are the main abrasive grains
     
    employed.
