potassium fluoroborate flux for soldering and brazing

   potassium fluoroborate flux (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 resinbonded abrasives for metal treatment 
• Production of soldering agents:  
  as component in fluxing agents for soldering and brazing 

   potassium fluoroborate flux  is used as a flux in the metal processing, surface treatment, and in the manufacture of aluminum, titanium and boron alloys. It is also used as a component for the fabrication of grinding wheel and abrasive disc to reduce the operating temperature, as a fire retardant for cotton and artificial fiber, and an erodent for the removal of exposed lead circuit board.

. Character

•    potassium fluoroborate flux  is white powder , nonhygroscopic and bittering.
•    potassium fluoroborate flux   is a hexagonal rhombus crystal when crystalized from aqueous solution.
• KBF4 relative density is 2.50, mp 529.5°C.
• It is slightly soluble in water and hot ethanol.
•    potassium fluoroborate flux  decomposes at melting point, reacts with strong acids such as sulfuric acid to produce boron trifluoride, reacts with alkaline metal carbonates to produce fluoride and borate.
