Effect of TiC Content and Sintering Process on Sintering Properties of AlN-SiC Composite Ceramics

Taking AlN and TiC as raw materials, the AlN-TiC composite ceramics were prepared by hot pressing sintering process, and the effects of TiC content and sintering process on sintering properties of AlN-SiC composite ceramics were studied. The results show that the composite ceramics didn′t generate new phase and consisted of AlN and TiC phases during sintering. The compact composite ceramics could be prepared after sintering at 1 900 ℃ for 1 h, the relative density reached more than 99% and the TiC content had no effect on sintering properties of the composite ceramics.
