Microwave Dielectric Properties of MgNb₂O₆ Ceramics Prepared via High Energy Ball Milling Method

Abstract:

The effects of high-energy ball milling and subsequent calcinations on the mixture of MgO and Nb₂O₅ are investigated. It is found that the pure MgNb₂O₆ phase can be synthesized at 800 °C for 5 h by using high-energy ball milling method. MgNb₂O₆ ceramics were prepared at 1220 °C by using calcined powders of milled 15 h, which is lower 100 °C than that required by using the conventional solid state reaction method. The microwave dielectric properties of MgNb₂O₆ ceramic with εr = 19.7 and Qf = 29 044 GHz were obtained by the High-energy ball milling method, which made it a potential candidate for application.
