研究了SiC 晶须在Ｍｕｌｌｉｔｅ浆料中的分散行为．通过沉降实验和流变学测试讨论了ｐＨ值，分散剂对SiC 晶须分散性质的影响．结果发现，晶须的加入影响了浆料的流变性能．当ＰＨ＝１１，分散剂含量为5wｔ％时，可获得分散性较好的浆料．本分散工艺促进了晶须在Ｍuｌｌｉｔe浆料中的分散，提高了浆料的结构均匀性．
The character of dispersion of SiC whiskers in mullite slurry was studied. The relationship 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.
