Popis: Based on the latest thermodynamic data on boron and 18 boron‐containing compounds computer‐based simulation of boron trichloride‐hydrogen system equilibration was made in 1000–6000 K temperature range, NH2/NBCl2=2−50 and 101Pa–1.01 MPa pressure range.The results made it possible to set applicable parameters of plasma‐chemical boron production process.A plasma‐chemical electric arc pilot plant of 80 kW power was designed and tested. The method of boron trichloride reduction with hydrogen was developed, providing boron yield up to 60% and boron trichloride consumption up to 97% due to recirculation. Amorphous boron purity (immediately after production) was 94.8±1wt%. Crystalline boron purity was 98.5–99.0 wt.%.
