摘要：

High-purity Ti-Al-C ternary layered ceramics were prepared by a pressureless sintering process using TiC, Al and Ti powder as raw materials, and the influences of sintering temperature, sintering time and sintering aids on the preparation of Ti-Al-C system layered ceramic were investigated. The results show that the increase of sintering temperature and time can reduce the generation of impurity phase. More than 80% Ti-Al-C ternary layered ceramics were obtained at 1400℃ for 3h without adding additives. Under this condition, a small amount of Si or Sn powder was added to obtain a high-purity Ti-Al-C ternary layered ceramic. can obtain Ti3AlC2 ceramic with a purity of 99% can be obtained when the raw material powders of TiC: Al: Ti: Si (2: 1.2: 1: 0.1) are incubated at 1400℃ for 3h, and Ti3AlC2/Ti2AlC composite ceramic with a purity of >99% and Ti3AlC2 as the main crystal phase can be obtained when the raw material powders of TiC: Al: Ti: Sn (2: 1.2: 1: 0.1) and TiC: Al: Ti: Sn (1: 1.2: 1: 0.1) are prepared at 1 400℃ for 3 h. © 2019, Editorial Department of Journal of the Chinese Ceramic Society.
