Abstract

The influence of CuO on the grain growth kinetics, densification and microstructure of YBa2Cu3O7-δ was studied. The YBa2Cu3O7-δ material with sufficient liquid phase revealed a grain growth exponent of about 0.25 after isothermal annealing at 990°C. The addition of CuO greatly enhanced the densification during sintering through the presence of the liquid phase. A microstructure containing highly aligned grains (d > 200 μm) was produced by a compositional gradient of CuO powder.
