The key problem to prepare carbon nanotubes (CNTs) reinforced ceramic matrix composites is how to break up massive agglomerates of CNTs and disperse uniformly CNTs. We obtain the CNTs-Al2O3 composite powder by shear treatment on melted CNTs-Al2O3-agents mixture. Microstructure observations of CNTs-Al2O3 composite powder show that CNTs can be dispersed uniformly by shearing process. The rheological results also affirm the conclusion. According to the rheological theory, we build the ideal dispersion model of CNTs-Al2O3 suspension system and discuss the dispersion mechanism.
