摘要：
The suspension of multi-phase and multi-scale nanocomposite ceramic powders that showed long-term stability was obtained via a series of dispersing technologies including ultrasonic stirring, ball milling and adding dispersant etc. The effectiveness of preventing the suspension from agglomeration by adding the dispersant PMAA-NH4 is better than that of adjusting the pH value of the suspension with aqueous ammonia and hydrochloric acid or adjusting the pH value with aqueous ammonia and hydrochloric acid together with adding PMAA-NH4. A special microstructure was found through TEM that an alpha-Al2O3 particle is environed by TiN and Ti (C7N3) particles.
