摘　　要：纳米Al_2O_3浆料容易形成絮凝团聚,使其应用在很大程度上受到限制,故稳定并分散纳米Al_2O_3颗粒显得至关重要。综述纳米Al_2O_3颗粒分散机理的研究进展以及发展现状,详细介绍六偏磷酸钠(SHMP)的静电稳定机制、聚乙二醇(PEG)的空间位阻稳定机制、聚丙烯酸钠(PAAS)的静电和空间位阻共同稳定机制。通过3种不同的分散机制使悬浮液稳定,避免浆料中纳米Al_2O_3颗粒发生团聚。最后对未来纳米Al_2O_3颗粒分散性方面的研究工作进行展望。Nano-Al2O3 particles are easy to agglomerate,which limits its application to a large extent,so it is very important to stabilize and disperse the Al2O3 ceramic slurry. This article summarizes the research progress and development status of the dispersion mechanism of nano Al2O3 particles. Electrostatic stabilization of SHMP,steric stabilization of PEG,electrostatic and steric stabilization of PAAS are introduced in detail. The suspension can be stabilized by three different dispersion mechanisms,and the aggregation of nano Al2O3 particles in the slurry is avoided. Finally,the future research work on the dispersion of nanoAl2O3 particles is prospected.
