Origin, Transformation and Control of the Inner Stress in the Green Bodies Prepared by Ceramic Colloidal Forming Processing

Abstract:

Article Preview

The origin of the inner stress in the ceramics green bodies prepared by colloidal forming was studied. The results show that the inner stress originates from the nonuniform shrinkage during the solidification of the precursor suspension and the drying of the green bodies, and the gradients of temperature, initiator concentration and moisture are the important original factors causing the inner stress. The inner stress could result in cracks in the green bodies during debinding.
