✦ Synopsis

Spark plasma sintering (SPS) of a commercially available granulated zirconia powder has been investigated. The ''relative density/ grain size'' trajectory, or ''sintering path'', has been established for a constant heating rate (50 °C/min) and a constant applied pressure (100 MPa). In addition, an attempt has been made to identify the mechanism(s) that could be invoked for the control of densification during the SPS experiments.
