Self-healing ceramic material with reduced porosity and method for preparing the same
The present invention provides a self-healing ceramic material with reduced porosity and a method for preparing the same. The self-healing ceramic material comprises the following components by volume: 60-85 parts by volume of Al2O3, 10-20 parts by volume of TiN, 10-20 parts by volume of TiSi2, 0.1-1 parts by volume of MgO, and 0.1-1 parts by volume of Y2O3. Wherein, Al2O3 serves as a matrix, TiN and TiSi2 act as repair agents, and MgO and Y2O3 function as sintering aids. The repair function is realized by adding TiN and TiSi2, which have repair capabilities, to the ceramic matrix, enabling the ceramic material to heal cracks. TiN plays the main role of repair function, and TiSi2 assists in the repair and helps reduce the formation of surface pores.
