摘　　要：选用纳米粉SiC为原料,分别采用单一静电稳定机制、加入PEG的空间位阻稳定机制和加入PMAA-NH4的电空间稳定机制,制备成1vol%的SiC水悬浮液.通过Zeta电位、沉降实验和粘度测定及粒度分析等手段,最终分别获得了碱性条件下高分散、高稳定的SiC水悬浮液.By choosing nanoSiC as the raw material,1 vol% nanoSiC aqueous suspension is obtained by using stabilization mechanisms including single electrostatic, steric ( by PEG ) and electrosteric ( by PMAA-NH4)respectively.The suspension is studied by means of Zeta potential measurements,sedimentation experiments, viscosity measurements and particlesize analysis,etc.Then,the highly dispersed and stabilized nanoSiC aqueous suspension under alkaline condition is obtained.
