This study investigated calciothermic cobalt boride (Co_xB) powder production in molten salt, starting from cheap oxide compounds, without pre-treatment by in situ Ca production via electrolytic reduction of CaO. Firstly, calciothermic Co_xB production in a molten salt environment was examined theoretically in detail, and the electrochemical behaviors of CaO and CoO in CaCl₂ were examined via cyclic voltammetry (CV). Based on the CV results, the cathodic reduction of CoO occurred in one step at − 0.30 V, and CO₂ formation occurred in two stages. After theoretical and CV analysis, the effects of temperature (1123–1323 K) and duration (30–60 min) on particle synthesis were investigated. While Co was found in the particles produced at low temperature and short durations, with increasing duration and temperature, B diffusion increased, and all Co was transformed into Co_xB, and particles were found to be made up of Co₂B and CoB phases.

本研究调查了在熔盐中生产钙热硼化钴 (Co _x B) 粉末，从廉价的氧化物开始，无需通过电解还原 CaO 进行原位 Ca 生产的预处理。首先，从理论上详细研究了熔盐环境中的钙热Co _x B 生成，并通过循环伏安法（CV）研究了CaCl _{2中CaO和CoO的电化学行为。}根据 CV 结果，CoO 的阴极还原在 - 0.30 V 下一步发生，CO ₂形成分两个阶段。在理论和 CV 分析之后，研究了温度（1123-1323 K）和持续时间（30-60 分钟）对粒子合成的影响。而在低温和短时间产生的颗粒中发现Co，随着时间和温度的增加，B扩散增加，Co全部转化为Co _x B，颗粒由Co ₂ B和CoB相组成.
