Abstract
- The influence of BaCu(B<subscript>2</subscript>O<subscript>5</subscript>) (BCB) addition on the sintering temperature and microwave dielectric properties of ZnO-2TiO<subscript>2</subscript>-Nb<subscript>2</subscript>O<subscript>5</subscript> (ZTN) ceramic has been investigated using dilatometry, x-ray diffraction, scanning electron microscopy, and microwave dielectric measurements. A small amount of BCB addition to ZTN can lower the sintering temperature from 1100°C to 900°C. The reduced sintering temperature was attributed to the formation of the BCB liquid phase. The ZTN ceramics containing 3.0 wt.% BCB sintered at 900°C for 2 h have good microwave dielectric properties of Q × f = 19,002 GHz (at 6.48 GHz), ε<subscript>r</subscript> = 45.8 and τ<subscript> f</subscript> = 23.2 ppm/°C, which suggests that the ceramics can be applied in multilayer microwave devices, provided that Ag compatibility exists.
