Summary

The manufacture of reliable high performance structural ceramics requires a good understanding of the different steps involved in the process. The presence of nonuniformities in the distribution of the polymeric binder could give rise to local fluctuations of density that could produce failure of the ceramic piece. Specimens prepared from Al2O3 with 15 and 2.5% w/w binder were imaged using NMR techniques in order to measure binder distribution maps. The results show that NMR imaging could be a useful technique to nondestructively evaluate the quality of green-state specimens.
