Transformation‐toughened zirconia compacts have been produced using a pressure‐induced phase of zirconia as the toughening agent. The high‐pressure phase is retained metastably after compaction at 8.6 GPa and sintering at temperatures as low as 250°C. High‐pressure processing offers potential for new transformation‐toughening phases in other ceramic materials.
