| 摘 要： | 基于圆极化天线原理建立了一种新型的多模谐振腔加热系统。结构设计中采用３ｄＢ电桥及相互垂直的耦合孔，从而在谐振腔内形成极化电磁波，显著改善加热均匀性，与合适的助热保温结构相配合，成功地对ＺＴＡ，ＺｒＯ２，Ｓｉ３Ｎ４等先进陶瓷进行烧结。建立的加热系统加热效率高，结构简单，操作方便。

| Abstract: | A new type of microwave heating system with a multimode cavity was constructed based on the principle of circularly polarized antenna.Polarized electromagnetic fields were formed inside the cavity by the application of a 3dB bridge and two coupling apertures perpendicular to each other,which greatly improved the heating uniformity.Advanced ceramics,such as ZTA,ZrO 2,Si 3N 4,etc. were successfully sintered using the system in combination with a suitable thermal insulator.The new system was characterized by high efficiency,simple construction and good performance. |
