Rezumat:

Nanometer-sized calcium titanate (CaTiO3) particles were synthesized by the modified sol-gel method, from Ca(CH3COO)2 and Ti(C4H9O) an ideal cation stoichiometry for CaTiO4 perovskite. EDTA was used like chelating agent. XRD analysis for their crystal structure and TEM for their texture characterized the materials obtained after heating in the range 600-10000C. The TEM photographs reveal nanoparticles in the size range 50-450 nm with a mean diameter found at 120 nm.
