| Abstract: | In the paper, the effects of many processing factors on AlN ceramic material were investigated. A proper process was developed to manufacture AlN ceramic with high thermal conductivity and better dielectric properties. Microstructure of AlN ceramic was observed and some conclusions were obtained. AlN ceramic supporting bar, collector and output window were processed and used in microwave tubes. Some experiences were obtained. |
