The synthesis of boron-containing nanoparticles inert at room temperature

Boron-containing (C₂B₄H₂) _n nanoparticles with size 6.7, 7.8, and 10.8 nm inert at room temperature were synthesized. The synthesis was performed by the pyrolysis of gaseous carborane C₂B₄H₆ at 1200–1280 K and the initial carborane pressure (5–25) × 10⁻³ MPa. An analytic dependence relating the size of nanoparticles to the temperature and initial carborane pressure was obtained.
