Effect of binder content on shrinkage behavior of a multilayered ceramic substrate

Among the many variables governing the shrinkage of ceramic substrate, pack ing density is the most important. The effect of binder content on the shri nkage behavior of a free and constrained sintering glass-ceramic multilayer ed substrate is investigated. For lower packing density, the packing of cer amics within the glass-ceramic green sheets was looser and a higher sinteri ng shrinkage was obtained. A good agreement between the calculated and expe rimental vertical shrinkage is obtained for constrained sintering glass-cer amic substrates using the proposed analytical procedure.
