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 For price, specification and more information please contact us.
Using nay as the raw material, usy is made through such a series of processes as ammonium salt treatment, hydrothermal ultrastabilization and chemical dealumination and silicon reinsertion. It is not only an active component of catalytic cracking catalysts, but also a crucial active component in hydrocracking catalyst, through which high quality diesel, aviation kerosene and naphtha can be produced.
