Abstract
- A novel CuO-ZnO-B 2 O 3 -Li 2 O glass-ceramic was prepared by solid phase method, and. Its phase transition, sintering and dielectric performance was studied. No crystalline phase is observed for the specimen sintered at 560 °C. However, the samples sintered at 580 °C and 600 °C, consist of ZnB 4 O 7 and Cu 2 B 4 O 7. And the Li 2 CuB 4 O 8 appears with further increasing temperature. The ε r and τ f change slightly but the Q × f value alter greatly with firing temperature. The glass-ceramic fired at 620 °C possesses optimum properties with ε r = 3.33, Q × f = 17,724 GHz and τ f ≈ 0 ppm/°C. Furthermore, the as-prepared glass-ceramic exhibits good co-firing compatibility with Ag and Al electrode. These properties qualify the dielectric material as promising alternatives for wireless communication applications. [ABSTRACT FROM AUTHOR]
