Abstract
The principles of rate controlled sintering (RCS) were applied to compacts from a ZrO2(Y)-TZP powder. The time-temperature profiles for RCS of this material can be approximately predicted from a few dilatometer experiments carried out at constant rate of heating, if the densification- and heating rates remain within some certain limits. In this way optimum sintering cycles could be designed, leading to advantages concerning density and grain size, compared to conventional isothermal sintering. Limitations for using the full potential of RCS for the investigated practical system arise from processing defects, which cannot be healed during sintering.
