Abstract
The phase transformations of zirconia are an important factor that makes it a valuable material for numerous applications in ceramics. The factors triggering the onset of the phase transformation are controversial. Evidence is presented to show that surface sites that adsorb oxygen at low temperatures (298-500 K) are responsible for causing the tetragonal → monoclinic transformation at low temperatures. The incorporation of sulfate covers these sites and inhibits the tetragonal → monoclinic transformation.
