在这项研究中，一个新的电解熔体反应器，用于大规模和低温生产无定形元素硼粉（ABP）配备了一个旋转的星星阴极电极在石墨坩埚，这减少了硼盐的均匀化时间的报道。电化学沉积系统设计用于生产高纯度ABP，容量高达25 kg，可根据商业生产的不同百分比范围内的各种盐的不同组合。该系统的创新之一，星星型铁阴极双向旋转，并在需要时上下定位，这要归功于运动传动轴。在设计了熔融反应器后，采用一定比例的KCl、KBF4和B 2 O3盐进行了ABP的生产.结果，KCl、KBF 4和B 2 O 3混合盐的熔化时间为3. 7 h，生产在480度的低温下进行。在生产中测得的最高阴极电流密度为1.083 A cm− 2。分析表明，产生了无定形结构的高纯度（95.6%）元素硼（B）颗粒。采用XRD、SEM、EDS、FTIR等分析手段对高纯B的形貌和化学成分进行了表征。
In this study, a new electrolysis melt reactor for large-scale and low-temperature production amorphous elemental boron powders (ABP) equipped with a rotating star cathode electrode in a graphite crucible, which decreases the homogenization time of the boron salts is reported. The electrochemical deposition system has designed to produce high-purity ABP up to 25 kg capacity for a different combination of various salts in different percentage ranges in accordance with commercial production. One of the innovations of the system, the star type iron cathode is rotated bidirectionally and positioned up and down when desired, thanks to the movement transmission shaft. After the design of the melted reactor, ABP has produced using certain proportions of KCl, KBF 4, and B 2 O 3 salts. As a result, the melting time of KCl, KBF 4, and B 2 O 3 mixed salts was 3.7 h, and the production took place at a low temperature of 480 degrees. The highest cathode current density in production was measured as 1.083 A cm− 2. The analyses revealed that an amorphous structured high purity (95.6%) elemental boron (B) particles were produced. The morphology and chemical composition of the highest purity B has characterized using XRD, SEM, EDS, and FTIR analysis.
