Abstract: Because themicro-nano barium titanate ceramics (BaTiO3) are the key materials of the multilayer ceramic capacitors (MLCCs), the researchers focus on synthesizing them controllably. In this work, the micro-nano BaTiO3 ceramics with different sizes were prepared by a self-assembly sintering method. We have researched the effects and application scopes of this method to synthesize the micro-nano BaTiO3 ceramics controllably by investigating the relative density, grain size, and dielectric properties. We can controllably prepared the ceramics with different grain sizes by the binary particle size self-assembly sintering method, that is, selecting the BaTiO3 powder sizes and combination method reaso-nably. Although the relative density of the ceramics were improved via the ternary and quaternary grain size self-assembly sintering methods, the controllability of grain size were reduced simultaneously. Therefore, it is beneficial to synthesize the micro-nano BaTiO3 ceramics controllably though the binary particle size one.
