%X Direct Coagulation Casting (DCC) is a near net shape forming technique for complex shaped ceramic green bodies with high quality and homogeneity. Double layer stabilized concentrated ceramic suspensions are solidified by shifting the suspensions pH towards the isoelectric point using the in situ enzyme-catalyzed reaction, which minimizes the repulsive forces between the suspended particles. The remaining, attractive Van der Waals forces form a stiff, wet green body. One of the most important process in DCC is preparing the ceramic suspension with high solids loading (>55vol% ) and low viscosity, the other key technique is controlling the enzyme-catalyzed reaction .
