Tóm tắt

A nanometer‐thick BaTiO3 coating layer has been prepared on spherical Ni. The BaTiO3 coating effectively retards the low‐temperature sintering between Ni particles and improves the resistance against Ni oxidation. This technology provides a useful tool to fabricate highly integrated multilayer ceramic capacitors (MLCCs). The Figure shows the nanometer‐thick BaTiO3 hollow spheres after core (Ni) removal.
