Electrokinetic Behavior of Hydrophobic Aluminium Nitride Powder
抗水性AlN粉体的电动特性研究

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.
