Monoclinic zirconia was pressed to approximates 20,000 atm at >1800 deg C, quenched, fired for 1 hr at 1350 deg C, and quenched. X-ray diffraction patterns were obtained while quenching was repeated through the phase transformation temperature range 800 to 1240 deg C; the results show that the new monoclinic-tetragonal phase transformation is shifted to 950 to 1000 deg C and that the tetragonal phase is stabilized at low temperitures.
