Ammonium tetrafluoroborate - NH₄BF₄ (CAS: 13826-83-0)

Ammonium tetrafluoroborate is a white to colourless crystalline powder. It is an ionic compound that can be synthesized by reacting boric acid and 2 equivalents of ammonium hydrogen fluoride.

Ammonium tetrafluoroborate is used in manufacturing of plastics as flame retardant, metallic plating, magnesium flux, soldering flux and are quenching for circuit breakers. It is also being used in synthesizing different organic salts and ionic liquids, which in turn can be used as a green solvent in chemical reactions. The chemical can also be used in the aim for a better leaching resistance of borate-treated wood. It is also used as a catalyst, in electrochemical synthesis, additive in catalytic systems, reductive dehalogenation of aromatic iodides, inversion of chiral amines and in steel and alloy industry.

Hypophosphorous acid 50% - H₃PO₂ (CAS: 6303-21-5) 

Hypophosphorous acid 50% an ionic compound that can be synthesized by reacting boric acid Intermediates hydrofluoric acid Intermediates then adding additive hydroxide. The most general method to prepare hypophosphorous acid is by hydrolysis of dialkyl phosphonate to phosphonic acid with concentrated HCl solution.

Hypophosphorous acid is used as a bleaching or decolorizing agent for plastics, synthetic fibres, and chemicals and also as a colour stabilizer and decolourizing agent in the manufacture of several plastics and chemicals. In electroplating it is used as a wetting, emulsifying or dispersing agent. The substance is used as an acidifying compound, chemical reducer, anti-oxidant, catalyst, in synthesis and electroless nickel plating and as a polishing agent.

Potassium tetrafluoroborate - KBF₄ (CAS: 14075-53-7)

Potassium tetrafluoroborate is a white ionic powder that is hygroscopic and incompatible with oxidizing agents. It is an ionic compound that can be synthesized by reacting potassium hydroxide with boron trifluoride.

It is used as an active filler in resin-bonded abrasives for metal treatment, as a component in fluxing agents for brazing and soldering, but also as a component in fluxing and grain refining agents for magnesium and aluminium. Potassium tetrafluoroborate is also used as an active filler in the preparation of resin-bonded . Abrasives and for extraction, refining and processing of metals in the chemical industry. In addition, it can be used as additive in alloying industry and welding agent and in the production of fluxing agents for brazing and soldering. It is also being used in synthesizing different organic salts and ionic liquids, which in turn can be used as a green solvent in chemical reactions.

Sodium hexafluorosilicate - Na₂SiF₆ (CAS: 16893-85-9)

Sodium hexafluorosilicate is an ionic and inorganic compound that can be synthesized by using neutralization of solutions of hexafluorosilicic acid with alkali metal bases.

The compound is mainly used in water fluoridation. Viscosity modifier for solution, suspension or emulsion. Dispersing aid for insoluble solids. Forms a gel in water. Films from aqueous or organic solutions have high tensile and cohesive strength. It is used in some countries as additives for water fluoridation, opal glass raw material, ore refining, or other production of other fluoride chemical, e.g. sodium fluoride, cryolite, or aluminium fluoride. 

Sodium hypophosphite – NaH₂PO₂ x H₂O (CAS: 10039-56-2)

Sodium hypophosphite is an ionic compound that can be synthesized by reacting barium hypophosphite with sodium sulphate.

It is mainly used as a reducing agent in electroless nickel plating, but also in electroless plating copper, to substitute conventionally used formaldehyde with the more environmentally friendly sodium hypophosphite. It is also used as a whitening agent, catalyst in the fibre-glass industry, flame retardant and in polymerization, paint and coating.

Sodium tetrafluoroborate - NaBF₄ (CAS: 13755-29-8)

Sodium tetrafluoroborate is a white ionic powder that is hygroscopic and reacts with strong oxidizing agents. In addition, it is an ionic compound that can be synthesized by reacting fluoroboric acid with sodium hydroxide or sodium carbonate.

Sodium tetrafluoroborate is one of the handiest reducing agents, especially for organic compounds in nonaqueous solvents. It has been used to reduce ketones, aldehydes, Schiff bases, carboxylic acids and esters, acid chlorides, disulfides, nitriles, and inorganic anions. For many of these substrates, only gentle reaction conditions are required. In the industry, sodium tetrafluoroborate is used in brazing, in the manufacture of glass and frits, treatment of glass and metal surfaces, sand casting of aluminium and magnesium. In addition, it can be used in wood preservative treatment. It is also being used in synthesizing different organic salts and ionic liquids, which in turn can be used as a green solvent in chemical reactions. In the 1940s it was introduced for wartime applications and was a very important reagent by 1970, which qualified it for a lengthy review.
