摘要：

The sintering behavior and dielectric characteristics of a titanium dioxide (TiO2) were investigated by adding CuO. The addition of CuO lowered the sintering temperature of the TiO2. At a given temperature, the densification and grain growth rate for a TiO2 with CuO were enhanced, compared with those of pure TiO2. The results suggest that CuO acts as an activator for the sintering of TiO2. Dielectric constant and loss were also examined for both pure and CuO added TiO2 samples. The variations of dielectric constant and loss were discussed in terms of grain size, porosity, and oxygen deficiency.
