摘　　要：介绍了纳米陶瓷粉体的几种主要分散机理:双电层(静电)稳定机制,空间位阻稳定机制,静电位阻稳定机制;根据不同的稳定机制可以得出相应的影响因素及控制方法。概述了目前纳米陶瓷粉体分散的研究现状,讨论了诸如表面活性剂、pH值、电解质等对分散效果的影响。In this paper, the dispersion mechanisms of nano ceramic powders were introduced,mainly including electrostatic stabilization, steric stabilization and elctrosteric stabilization. And corresponding factors and control method could be induced from these mechanisms. The present research stage of nano ceramic powders was summarized, discussing the influence of surfactant, pH value, and electrolyte.
