A　sol-gel-hydrothermal　method　has　been　adopted　to　synthesize　the　shape-controlled　SrTiO3　crystallites.　A　series　of　shape　evolutions　of　SrTiO3　crystallites　varied　gradually　from　the　unfeatured　conglomeration　through　eight-pod　star-shaped　particles　to　cubic　crystals　and　have　been　recorded　based　on　transmission　electron　spectroscopy　(TEM)　and　scanning　electron　microscopy　(SEM)　observations.　The　faster　growth　rate　along　[111]　direction　in　the　SrTiO3　lattice　resulted　in　the　(111)　plane　disappearing,　while　(100)　plane　remained　to　form　SrTiO3　cubes　owing　to　the　relative　lower　growth　rate.　The　experimental　results　suggest　that　the　building　blocks　with　desired　architecture　can　be　selectively　synthesized　by　programming　the　growth　conditions　in　the　initial　synthetic　scheme.　(c)　2006　Elsevier　B.V.　All　rights　reserved.
