摘　　要：通过对 ξ电位和粘度的测量 ,研究了pH值、粒度分布、分散剂及纯度对浆料流变性的影响。结果表明 ,SiC浆料的等电点在 4.3左右 ,在等电点附近 ,浆料易发生聚沉。Through the measurement of ξ potentials and viscosity,the effects of pH values,particle size distribution,impurities,and contents of dispersants on the rheological properties were studied in this paper.The results showed that the IEPof SiC slurry was around 4.3,in which the slurry was inclined to sediment.The dispersant B and purification could greatly improve the rheological properties of SiC slurry.
