纳米六方三水铝石种子是在 85°C 下由溶解的氧化铝醇盐的混合物生长而成。离心使多分散性降低 30%。通过将种子添加到新鲜的醇盐混合物中并加热，可以进一步生长种子。重复该过程数次以获得直径为 570 nm ± 11%、厚度为 47 ± 23% 的颗粒。没有观察到尺寸限制的迹象。由此获得的颗粒可以容易地形成柱状相。通过共焦显微镜可以看到溶液中的单个三水铝石颗粒。
Nanosized hexagonal gibbsite seeds are grown from a mixture of dissolved alumina alkoxides at 85 °C. Centrifugation reduces the polydispersity by 30%. The seeds can be grown further by adding them to a fresh alkoxide mixture and heating it. This procedure was repeated several times to obtain particles of 570 nm ± 11% diameter and a thickness of 47 ± 23%. No indications of a size limit were observed. The thus obtained particles may form easily a columnar phase. Individual gibbsite particles in solution can be seen by confocal microscope.
