Notes:
A high solid loading of dispersed silicon nitride slurry was prepared with various dispersants,which allowed a stable silicon nitride suspension with sintering additives (cordierite) in alkaline regionsto a solid content of 45 vol%. Gum arabic, PMAA-NH4, TMAH, PAA-NH4 and their composites wereselected as dispersants. The results suggested that the composite dispersant which was obtained usingPAA-NH4 and TMAH with the ratio in 4:1 was more effective in aqueous silicon nitride powdersuspensions system than simplex dispersant. The green bodies derived exhibited a mechanical strength ashigh as 8.7MPa and SEM photos revealed that the green body also had a high homogeneity
