FIELD: process engineering.
SUBSTANCE: invention relates to chemical industry, particularly, to production of new superconducting boron-containing compounds. Proposed boride including lithium, vanadium and boron and having transition to superconducting state at 27 K is produced by sold-phase high-temperature synthesis of initial components made up of the mix of vanadium and boron powders with molar ratio of 1:2 and 0.3-0.5 mol of metallic lithium at 1000°C in vacuum of 10-4 Pa for 5 minutes.
EFFECT: production of new superconducting boron-containing compounds with transition to superconducting state at notably higher temperatures.
