Abstract
BPO4 has low εr (< 5) and an acceptable high Q × f value, while extremely poor sinterability. It showed that, in the present work, an appropriate addition of ZnO could simultaneously enhance the sinterability and microwave dielectric properties of BPO4 ceramic. The addition of ZnO led to the formation of zinc-phosphates, a small amount of zinc borate, and B2O3 secondary phases, which increased with increasing the ZnO addition. A small amount of ZnO addition increased the dielectric permittivity, Q × f value, and more negative τf value. The 0.97BPO4-0.07ZnOceramic exhibit good combined microwave dielectric properties with εr ~ 4.75, Q × f ~ 55,000 GHz, and τf ~ -42 ppm/℃after sintering at 1150 °C/2 h.
期刊介绍:
The Journal of Materials Science: Materials in Electronics is an established refereed companion to the Journal of Materials Science. It publishes papers on materials and their applications in modern electronics, covering the ground between fundamental science, such as semiconductor physics, and work concerned specifically with applications. It explores the growth and preparation of new materials, as well as their processing, fabrication, bonding and encapsulation, together with the reliability, failure analysis, quality assurance and characterization related to the whole range of applications in electronics. The Journal presents papers in newly developing fields such as low dimensional structures and devices, optoelectronics including III-V compounds, glasses and linear/non-linear crystal materials and lasers, high Tc superconductors, conducting polymers, thick film materials and new contact technologies, as well as the established electronics device and circuit materials.
