Description
Summary:Constrained sintering, as seen in the sintering of laminated structure or thick film, inherently involves the problem of macro- and micro-defect formation such as cracks and/or delamination. The origin of these defects lies in mismatches of sintering shrinkage between materials. Sintering under centrifugal acceleration has been found to be a successful strategy for eliminating these mismatches, leading to a crack-free homogeneous microstructure. This distinctive feature of centrifugal sintering arises from anisotropic shrinkage that is caused by chief densification progress along the radius of rotation. (Material: barium titanate.)
