The effect of YO1.5 dopant on unit-cell parameters of ZrO2 (YO1.5=0 to 14.6 mol%) were examined by the X-ray whole-powder-pattern decom-position technique. The unit cell of monoclinic ZrO2 has the largest expansion along the direction perpen-dicular to (100). The rate of increase of the unit-cell volume of monoclinic ZrO2 with YO1.5 content is greater than that of tetragonal ZrO2 and comparable to that of cubic ZrO2. |
