通过控制Al:B原子比和合成温度，采用一步燃烧法成功合成了两种硼酸铝纳米线Al4B2O9和Al18B4O33。两种纳米线都是单晶，但生长习性不同。纳米压痕测试直接在单个纳米线上进行，以揭示其机械性能。Al(18)B(4)O（33）纳米线的弹性模量比Al(18)B(4)O（33）纳米线降低了70%，Al18B4O33纳米线的硬度和弹性模量比Al4B2O9纳米线高。
Two kinds of aluminum borate nanowires, Al4B2O9 and Al18B4O33, were successfully synthesized by a one-step combustion method through control of the Al:B atomic ratio and synthesis temperature. Both nanowires are single crystalline but have distinguishing growth habits. Nanoindentation tests were performed directly on individual nanowires to reveal their mechanical properties. A 70% reduction in elastic modulus was found in Al(18)B(4)O(33)nanowires compared with their bulk counterpart, Al18B4O33 nanowires exhibited higher hardness and elastic modulus than Al4B2O9 nanowires.
