通过测量粉体在水溶液中的Zeta电位和颗粒尺寸，研究了引入不同的分散剂时抗水性AlN粉体的电动特性．结果表明，溶液的pH值和引入不同的分散剂均会导致抗水性AlN粒体的表面荷电状况及其在水溶液中的分散状况发生变化．NH4PA是一种适合抗水性AlN粉体水基流延用的有效分散剂，在碱性条件下添加该分散剂有利于抗水性AlN粉体在水溶液中的稳定分散．
Electrokinetic behavior of hydrophobic aluminium nitride (AlN) powder was studied by zeta potential and particle size measurement in aqueous suspension by introducing different dispersants. As a result, pH values and the types of dispersants affect the surface charge and the particle dispersion of hydrophobic AlN suspension. NH4PA, arnmonium poly(acrylic acid), is an available dispersant for aqueous tape casting of hydrophobic AlN powder, proper addition of which can lead to well dispersed hydrophobic AlN suspension.
