N2 - M-AlN (surface modified aluminum nitride powder) suspensions for aqueous gelcasting were prepared Using NH4PAA as dispersant. The effects of pH value, NH4PAA amount and solid content on the rheological behavior of M-AlN suspensions were investigated. The results showed that low viscosity M-AlN aqueous suspensions with high solid content up to 55 vol.% were obtained under the condition that the amount of NH4PAA was 0.9 wt. % of M-AlN powder, and pH value was about at 6.8. In spite of this, these suspensions still show a viscosity lower than 0.12 Pa·s at 100s-1, suggesting a good fluidity which can satisfy the requirement of gelcasting.
