摘要
The sintering of (Ba0.8Sr0.2)(Ti0.9Zr0.1)O3 (abbreviated as BSTZ) with different amounts of CuO, which is used as the liquid phase promoter for lowering the temperature required to densify BSTZ, is studied using two types of calcined powders. For 1050-degrees-C calcination, the calcined powder contains BaTiO3, SrTiO3 and some raw materials such as ZrO2 and BaCO3. With sintering, some residual raw materials form unknown phases or low-dielectric-constant compounds with CuO, causing the liquid phase effect of CuO to disappear. For 11 70-degrees-C calcination, the calcined powder completely forms ABO3 phases containing (Ba, Sr)TiO3 and BaZrO3. The sintering temperature for densification of ceramics is lowered, and the firing characteristics critically depend on the amount of CuO added and the sintering temperature.
