| Description | Journal: Materials Research Innovations BaTiO3–Cu ferroelectric/metal composite was successfully fabricated by sintering Cu2O-added BaTiO3 pellet under nitrogen gas flow. In the results of XRD analysis of the sintered body, it was found that cuprous oxide was reduced to copper in the atmosphere of 100 ml/min nitrogen gas flow, but was not reduced and remained as itself in air. Lattice parameter changes of the specimens sintered at 1280 °C in 100 ml/min nitrogen gas flow indicated that solubility limit of cuprous oxide (Cu2O) into BaTiO3 is thought to be less than 1 wt%. The melt from cuprous oxide is thought as a good sintering aid to densify BaTiO3. In this experiment, we determined the optimum sintering condition to get BaTiO3–Cu ferroelectric/metal composite with more than 95% of relative density. From the results of DTA and TG analysis, cuprous oxide is considered to dissociate into copper and oxygen gas and form the eutectic melt of BaTiO3–Cu at around 900 °C in more than 50 ml/min nitrogen flow rate atmosphere. |
