Abstract :
The 72% of the World boron reserves are in Turkey. The biggest portion of boron reserves leads the boron studies. Due to its important properties boron usage areas are extending. In this study the chlorine containing magnesium borate synthesis by solid-state method is investigated. The reaction temperatures were set between 500°C - 700°C. Magnesium chloride hexahydrate (MgCl2.6H2O) used as chlorine and magnesium source, magnesium oxide (MgO) used as magnesium source and boric acid (H3BO3) used as boron source. The effect on the synthesis by the molar ratio change of the raw materials was investigated. Synthesized minerals characterization analyses were done by the techniques of X-Ray Diffraction (XRD) and Fourier Transform Infrared Spectroscopy (FT-IR). From the results of this study the chlorine containing magnesium borate of boracite (Mg3B7O13Cl) was obtained. The side products of dehydrated magnesium borates namely magnesium borate (MgB4O7) and suanite (Mg2B2O5) were also formed. The formation of boracite was started at the reaction temperature of 500°C and the temperature increase effected the Mg3B7O13Cl formation positively.
