Preparation of Strontium Titanate Nanocube Particles using Complex Titanium Raw Materials and Their Accumulations

摘要

In this study, strontium titanate (SrTiO_3, ST) nanocube particles were successfully prepared, with a size of 12 nm, normal size distribution with standard deviation of 10 %, and sharp edge comer, by solvothermal method using complex titanium raw materials of TiO_2 and titanium isoproxide. Moreover, the well-dispersed ST nanocube slurry was also prepared using electric double layer with hydrochloric acid. Finally, using the ST nanocube slurry, ST nanocube accumulation was prepared by two kinds of forces of capillary force and absorption force by plaster. The obtained ST nanocube accumulation was not 3-dimentional aliened ST nanocube structure, but randomly piled structure.
