Direct synthesis of Li[BH4] and Li[BD4] from the elements

摘要: Abstract The direct synthesis of Li[BH 4 ] and Li[B 11 D from the corresponding elements at T  = 700 °C p (H 2 ) (or (D )) = 150 bar is demonstrated. chemical inertness boron thought to prevent its reaction with lithium hydrogen LiBH lower temperatures. We show, however, that kinetics can be enforced by a LiB 3 -like alloy Li 7 B 6 intermetallic compound, which are formed in inert argon atmosphere 330 450 °C, respectively. performed exposing Li–B mixtures defined pressure high stainless steel vessel adsorption monitored decrease. product identified X-ray powder diffraction.
