## Description

- description: AlLB14 (L=Li or Na or K) crystals were grown using LiF or NaF or KF
    and crystalline boron powders as the starting materials using high-temperature
    Al melt at soaking temperature 1573~1773 K for soaking time 5 h under an Ar atmosphere.
    A new compound AlNaB14 and AlLiB14 crystals were obtained from LiF or NaF and
    B powders, and the atomic ratios (n=B/L=2.0~4.0) of starting materials. AlKB14
    crystal was not obtained from KF and B powders as starting materials. The micro-Vickers
    hardness of AlLB14 crystals is 24(±1) GPa for AlLiB14 and 25(±1) GPa for AlNaB14.
    The oxidation initiation temperature of AlLiB14 was about 815 K, and the peak
    due to the exothermic reaction was about 960 K for AlLiB14 and about 990 K for
    AlNaB14. The final oxidation products were Li2B2O4, Al4B2O9, B2O3 and amorphous
    phases.
