摘要
Abstract
Polyethylene glycol 400 was used as wetting reagent for highly concentrated aqueous silicon nitride suspensions. The aim was to increase the solid loading of suspensions with low viscosity at normal processing conditions. Viscosity, hygrometric and ab-sorption measurements were carried out to research the wetting properties of the reagent in silicon nitride suspensions at high solid loading. The results show that the relative viscosity of the suspensions is decreased by using the wetting reagent PEG400, especially at solid loading of 60%(in volume). A model was established for particles in solution as spheres with equal diameter and sufficient packing to explain the function of PEG400.关键词
