Avogadrite Kbf4 Powder Reliable Abrasives Material Tetra

Fluoro Borate

 

Product Description


Synonyms : POTASSIUM BOROFLUORIDE;POTASSIUM

 

BOROFULUORIDE;POTASSIUM FLUOROBORATE;Avogadrite;Borate(1-),

 

tetrafluoro-,potassium;Borate(1-),tetrafluoro-,potassium;boronpotassiumfluoride;KB

 

F4;Potassium fluoborate;Potassium Tetrafluoborate;

 

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:

metals to be fluoride and borate;melting point 530°C

 

 

Potassium fluoroborate (KBF4) is 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 abrasives:
     
  • as active filler in resin-bonded abrasives for metal treatment
  •  
  • Production of soldering agents:
     
  • as component in fluxing agents for soldering and brazing
