• Zirconia is a material of high engineering importance and scientific interest. The most dramatic increase in its industrial applicability has been brought about by the discovery that the tetragonal to monoclinic (t RT m) transformation can be controlled by suitable material processing. Many studies of plasticity and toughening induced by the (t RT m) transformation have also been done in zirconia. A number of studies have also been examined at high pressures and temperatures using Raman spectroscopy. However, there has been little work on shock experiments and the details of the phase transition and equation of state under high-pressures are not well known. In this paper, we studied laser-shock compression of yttria-doped (3 mol%) tetragonal zirconia polycrystals (3Y-TZP) using Raman spectroscopy.
