Core-shell-structure Ag@BaTiO3 nanocomposite powders at different Ag/Ba molar ratios are prepared directly by the “organosol” process which gave us a great inspiration to fabricate metal-ceramic composites.The diameter of these core-shell nanoparticles was between 30 and 50 nm,with the crystalline Ag particles at the core(see the TEM images)with an average thickness of BaTiO3 shell being~5 nm.The existence of the core-shell structure is well-supported by the results of EDS analysis(Figure).
