STRUCTURAL PHASE CHANGES IN NANOCRYSTALLINE DISPERSE SYSTEMS Zr[O.sub.2] DURING FIRING UNDER THE ACTION OF A CONSTANT MAGNETIC FIELD

Sintering of a Zr[O.sub.2]-CaO nanocrystalline system under the action of a constant magnetic field within the temperature interval 1200-1400[degrees]C gives rise to predetermined changes in microstructure and morphology of the particles. A method is proposed for hardening Zr[O.sub.2](CaO) ceramics...

Description
Summary:Sintering of a Zr[O.sub.2]-CaO nanocrystalline system under the action of a constant magnetic field within the temperature interval 1200-1400[degrees]C gives rise to predetermined changes in microstructure and morphology of the particles. A method is proposed for hardening Zr[O.sub.2](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. Keywords: magnetic field, microstructure, porous ceramics.
