Development of PZT Suspensions for Ceramic Ink-Jet Printing

摘要

The direct ink-jet printing of ceramic powders requires the development of highly fluid suspensions of ceramic particles with viscosity < 40 mPas. Here we describe the development of two such ceramic suspensions, which contain up to 30% by volume of PZT particles in either an azeotropic mixture of MEK and ethanol or in an alkane wax at 120℃. The influence of various processing parameters on fluid rheology are investigated and trial fluids have been passed through an ink-jet printing head.
