Abstract The research is about synthesis process of CaB6 powder by molten salt electrolysis method. The synthesis temperature, electrolysis voltage, electrolysis time is identified. At the same time, under the conditions of different electrolysis time,the phase composition, particle size and shape of cathode products is analysised by X-ray diffraction and scanning electron microscope , experimental results show that synthesis process of CaB6 powder in CaCl2 molten salt system must have the basic conditions: protectiving environment of argon, electrolysis voltage is 3.0V, 900℃ insulation 30h, the range of CaB6 crystal particles size was 2μm～10μm, the morphology of particle is regular with rule cuboid massive crystal. The cathode electrolysis process conducted cyclic voltammetry scan analysis, a preliminary dynamic analysis and calculation to determine that chlorine borate proliferating to the cathode is control step of reaction.
