Barium fluoride
Formula BaF2 Description White powder or pieces. No odor.
Preparation Brief: Barium carbonate is reacted with dilute Hydrofluoric Acid in a reactor. Resultant reaction mass is centrifuged to remove water. Then dried in a dryer to remove moisture. To get fine powder of Barium fluoride, it is pulverized in a pulverizer.
Reaction: BaCO3 + 2HF → BaF2 + H2O + CO2↑
Uses Used as opacifier in vitreous enamels. Barium Fluoride is used as a molten bath component in aluminum raffination, as flux and preopacifying agent and as component of welding rod coatings and welding powders.

Uses As catalyst for preparing acetals, esterifying cellulose, to clean metal surfaces before welding, In Alzak Process for the electrochemical brightening of Aluminum, reagent for sodium in presence of magnesium & potassium ions, as solute in electrolytes for plating metals such as chromium, iron, nickel, copper, silver, zinc, cadmium, indium, tin, & lead (has high throwing power), Using as a pH modifier in baths for electroplating metals from Fluoborate solutions. Fluoboric Acid is used to clean Lead and its alloys prior to electroplating. It is used for cleaning and etching of metal surfaces due to the high solubility of oxide and silicate films that may be on the metal surfaces. It is used as stripping solution for removal of solder metal plating from baser metals. Small additions of fluoboric acid have been proposed for phosphating baths, particularly for light metals, because the protective coatings are thereby improved. Catalyst for alkylation's and polymerizations. reagent for sodium in the presence of magnesium and potassium ions, for making stabilized diazo salts (diazonium & tetrazonium fluoborates), 0.1-0.5% solution retards fermentation.

Potassium boron fluoride
(Potassium fluoborate, Avogadrite)
Formula KBF4
Description White, fine granular, free flowing crystals, colourless orthorhombic crystals Uses As an ingredient in Welding and Brazing-flux. As a key ingredient in grain refining salts for aluminium, and can be used separately or combined with Potassium Titanium Fluoride (K2TiF6) to form a grain refining flux. Titanium and other elements to form TiB2 and other borides that act as grain nucleating agents, providing a cast structure of fine grain. Grain refiners improve mechanical properties and prevent cracking in aluminium castings.
KBF4 is also used as a cleansing flux for nonferrous metals like aluminium and magnesium. In the molten state on the surface of molten metal it will absorb oxides and other surface debris. Once absorbed the oxide can be removed out of the furnace by surface skimming. It can also be combined with other salts to form fluxes. The fluorine content from the KBF4 increases fluidity of any molten flux. In addition, it is used as an atmospheric barrier over molten magnesium providing an inert cover, preventing rapid oxidation of the molten magnesium. KBF4 can also be used as an ingredient in welding, brazing, and soldering fluxes.
KBF4 is used as a binder/filler in abrasive products. It has a melt point that is ideal for use in grinding wheels and other abrasives where baking of the product is involved. In the semi-solid state it, in effect, glues the various grits together providing a matrix for the particle.

The fluoride ion inhibits many enzymes that contain iron, calcium, and magnesium. Several of these enzymes are involved in energy production in cells, as in the case of phosphatases and phosphorylases.
It is used chiefly as a flux in the electrolytic production of aluminium from bauxite as it effectively lowers down the melting point of alumina. As a flux in reworking of scrap aluminum. Manufacture of aluminium by electrolysis of aluminium oxide. Approximately 47 lb. Of Na3AlF6 is used per tone of aluminium produced. Constituent in glass making. It acts as a powerful flux because of its excellent solvent power for the oxides of silicon, aluminium and calcium and because of the low melting compositions it forms with many components. In the glass furnace cryolite is the most stable fluorine carrier. Properties

Tin fluoborate
(Stannous fluoborate)
Formula Sn(BF4)2
Description
A clear colourless or nearly colourless liquid free from extraneous matter. It is a substantially odourless liquid with excellent electroplating qualities.
Uses
As an electrolyte in electroplating tin from fluoborate solutions. The Stannous Fluoborate bath gives white, fine grained deposits which can be deposited directly on to brass, copper or steel. The tin is deposited from the stannous state and consequently the amount of tin deposited for a given amount of current passed is double than that obtained with alkaline baths. As a constituent of electrolyte for depositing Lead-tin alloys from fluoborate solutions.
