Structural Phase Changes in Nanocrystalline Disperse Systems ZrO2(CaO) During Firing Under the Action of a Constant Magnetic Field

Resumo

Sintering of a ZrO₂–СaO nanocrystalline system under the action of a constant magnetic field within the temperature interval 1200–1400°C gives rise to predetermined changes in microstructure and morphology of the particles. A method is proposed for hardening ZrO₂(CaO) ceramics and a quantitative estimation of its contribution into the changes of its mechanical properties and fine crystalline structure parameters. A possibility is demonstrated for using constant magnetic field for deliberate changes of microstructure and mechanical properties of porous ceramics.
