A Novel Temperature Induced Gelation Forming Method

摘要：

　　We describe the production of complex shaped ceramic green bodies with high strength and reliability using a novel forming method:temperature-induced gelation.Gelation is performed by moderately decreasing the temperature of the suspension,which induces in situ gelation and forms a network to bridge the suspended particles,leading to a stiff green body.The gelation mechanism is based on the separation of dispersant KD 1 from solvent or the collapse of adsorbed layer on particle surface,which depends on the stability of starting suspensions.
