| description | Relating to the technical field of ceramic material preparation, the invention specifically discloses a composite ceramic material containing carbon nanotubes and a preparation method thereof. The method includes the steps of: (1) dispersing carbon nanotubes in ethanol, and then putting the mixture into grinding equipment for grinding to obtain a carbon nanotube slurry; (2) adding a dispersant into the carbon nanotube slurry prepared in step (1), conducting ultrasonic dispersion for 10-20min, and then performing drying to obtain dispersant-doped carbon nanotubes; and (3) mixing the dispersant-doped carbon nanotubes prepared in step (2), a binder and ceramic powder, stirring the substances evenly, and then performing pressing to obtain a green body; and subjecting the green body to degreasing sintering, thus obtaining the composite ceramic material containing carbon nanotubes. The method can achieve full and even dispersion of carbon nanotubes in ceramic, and then improve the bending strength of the ceramic ma |
