NMR imaging of advanced ceramics during the slip casting process

Abstract

The slip casting process in advanced ceramics was observed using an NMR imaging system. After the Al2O3 water suspension (Al2O3 slip) was poured into the mould, cross section of the mould was imaged. In the sequentially taken NMR images the Al2O3 slip was clearly distinguishable from the deposit because of the difference in relaxation time T2 and an increase of the deposit thickness with time was observed. These results indicate that NMR imaging is useful in the nondestructive monitoring of the slip casting process.
