| Abstract: | The character of dispersion of SiC whiskers in mullite slurry was studied. The rela- tionship between pH value or/and dispersant and dispersion of SiC whisker was discussed via the sedimentation experiment and rheology test. The results show that the rheological properties of the mullite slurry are affected by the addition of the whisker. Well dispersed slurry can be obtained with pH value and dispersant content as 11wt% and 5wt%, respectively. The dispersion techniques in the study can improve the character of dispersion of SiC whisker in mullite slurry, increasing the structure uniformity of the slurry. |
