In this study, copper(II) fluoroborate, one of the special boron products, was synthesized by high energy impacted ball milling method and characterization studies were carried out by means of FTIR and BF − 4 ion selective electrode. Copper fluoride and elemental boron were used as reactants in the study. Mechanochemical method by means of ball milling was carried out, in a three-dimensional spex-type ball mill in an argon atmosphere. Specimens were prepared at different mole ratios and mechanically milled in a ball mill for a fixed time to determine the optimum mole ratio and the reaction period was optimized in the next step. As a result of the experiments, the most efficient reaction was obtained when reactant mole ratio (nB/nCuF 2 ) of 0.85:1 and reaction period of 1500 minutes. Copper(II) fluoroborate was produced with a yield of 84.5% under the optimum conditions.
