BaTiO3-Cu ferroelectric/metal composite was successfully fabricated by sintering a Cu2O-added BaTiO3 pellet using a 100 ml/min nitrogen gas flow rate. Abnormal grain growth was found to occur above 1280°C by scanning electron microscopy (SEM). Electron probe micro-analysis (EPMA) results indicated that crystalline spheres within abnormally grown grains were generated from excess titanium-contained BaTiO3 and copper melt. Transmission electron microscopy (TEM) revealed that copper metal had twins and that BaTiO3 had faceted boundaries.
