| Abstract: | The classification of phase transformation in ceramics is suggested. Thethermodynamic and kinetic criterions on the spinodal decomposition are introduced. Workson thermodynamics expression for the size effect on the martensitic transformation in ceramics containing ZrO2 and the application of the formal phenomenological theory to themartensitic transformation in MgO-PSZ, CeO2-TZP, Y2O3-TZP, BaTiO3-KTN,PbTiO3 and YBa2Cu3O7-x. are reviewed. It is pointed out that the isothermal transformationin ZrO2 containing ceramics and YBa2Cu3Oy may be the bainitic transformation with diffusional mechanism. |
