Preparation of M-AIN Suspensions for Aqueous Gelcasting

摘要：

　　M-AIN (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-AIN suspensions were investigated.The results showed that low viscosity M-AIN aqueous suspensions with high solid content up to 55vol.% were obtained under the condition that the amount of NH4PAA was 0.9 wt.% of M-AIN 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.
