Uniform hierarchical strontium carbonate (SrCO(3)) submicron spheres bearing detectable cavities on the surfaces and porous structures within the body were efficiently obtained, by a facile hydrothermal treatment (190 degrees C, 12 h) of the room temperature precipitate derived from Na(2)CO(3) and SrCl(2) solution. MgCl(2) and ethylene diamine tetraacetic acid (EDTA) disodium salt were used as the additives. The as-obtained submicron spheres were self-assembled by crystalline SrCO(3) nanoparticles under hydrothermal conditions. The present hydrothermally synthesized hierarchical SrCO(3) submicron spheres would enlarge the potentials of SrCO(3) micro-/nanostructures in the hierarchical architectures and porous materials family for further applications in the fields of catalysis, composites, adsorbents, and devices, etc.
