Product Description

Crystal Potassium Fluoroborate For Flux Application 2.47 Specific Gravity

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.
