摘要

CuO-based oxide mixtures were selected as sintering aid for (Ba,Ca)(Ti,Zr)O₃ ceramics. Both microstructure and dielectric properties of were remarkably influenced by BaCO₃-CuO flux type. With 1 wt% additive of BaCuO₂-2.5CuO eutectic phase, (Ba,Ca)(Ti,Zr)O₃ ceramics give high dielectric constant of 11000 and uniform grain size of 4 approx. 10 μm when sintered at 1130°C for 1 h. Different kinds of CuO-MO_x mixtures were also used to investigate the role of MO_x metal oxide in the grain growth and densification of CuO-added (Ba,Ca)(Ti,Zr)O₃ ceramics. The eutectic temperature between CuO and MO_x plays an important key in microstructure evolution. Both dielectric properties and microstructure can be further modified with doping secondary oxides.
