Zirconia ceramics is the strongest and toughest material among advanced ceramics.
Zirconia (ZrO2) has a monoclinic crystal structure at room temperatures but transforms to cubic and tetragonal structures at elevated temperatures. This transition can result in the development of stresses during cooling which negatively impact the strength of the material.
