摘要：

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.
