Nanocubes accumulations were built up by meniscus method and developed to achieve a dense structure. For the first attempt, strontium titanate (SrTiO3, ST) nanocubes were selected for the nanocubes accumulations. The ST nanocubes were prepared by a solvothermal method. For Strontium titanate nanocubes, Sr(OH)2 and titanium isopropoxide (TP) were used as starting materials and were heated at 240°C for 18h in an autoclave. Size distribution of TP-derived ST nanocubes was narrower than TiO2-derived ST nanocubes. Moreover ST nanocubes accumulations were prepared by a meniscus method. A dense ST nanocubes accumulation of over 1 μm was prepared at an angle of 50 degrees at 60 °C. The crystal structures were determined by X-ray diffraction (XRD) and the microstructures were observed by scanning electron microscopy (SEM).
