We report an experimental route for synthesizing perovskite-structured strontium titanate(SrTiO_3) nanocubes using an alkali hydrothermal process at low temperatures without further heating.Furthermore,we studied the influence of heating time(at 180℃) on the crystallinity,morphology,and perovskite phase formation of SrTiO_3.The SrTiO_3 powder,which is formed via nanocube agglomeration,transforms into cubic particles with a particle size of 120-150 nm after 6 h of hydrothermal sintering.The crystallinity and percentage of the perovskite phase in the product increased with heating time.The cubic particles contained 31.24at%anatase TiO_2 that originated from the precursor.By varying the weight ratio of anatase TiO_2 used to react with the strontium salt precursor,we reduced the anatase-TiO_2 content to18.8at%.However,the average particle size increased when the anatase-TiO_2 content decreased.

Durthermore, we studied the influence of heating time (at 180 ° C) on the crystallinity, morphology, and perovskite phase formation of SrTiO_3.The SrTiO_3 powder, which is formed via nanocube agglomeration, transforms into cubic particles with a particle size of 120-150 nm after 6 h of hydrothermal sintering. crystallinity and percentage of the perovskite phase in the product increased with heating time. The cubic particles contained 31.24 at% anatase TiO 2 that originated from the precursor. By varying the weight ratio of anatase TiO 2 used to react with the strontium salt precursor, we reduced the anatase-TiO 2 content to 18.8 at% .However, the average particle size increased when the anatase-TiO_2 content decreased.
