　　Direct coagulation casting via controlled release of high valence counter ions(DCC-HVCI),as a novel colloidal ceramic forming method,has been recently developed.Lead zirconate titanate(PZT)ceramics were prepared by DCC-HVCI using magnesium citrate as coagulating agent with glycerol diacetate as pH controller.Suspension with high solid loading were prepared using poly(acrylate ammonium)as dispersant agent.
