Dynamics of structural-phase states of nanocrystalline ZrO2(CaO) during sintering in a constant magnetic field
The structure, phase composition, and dynamics of phase transformations of nanosystems based on zirconium dioxide ZrO2(CaO) obtained by the plasma-chemical method have been studied. In order to lower the sintering temperatures and improve the physical and mechanical properties of ceramics, activation sintering of the ZrO2-CaO nanocrystalline system in an external magnetic field was applied. A constant magnetic field inside the furnace volume was created by a toroidal coil with a special symmetrized winding. Ceramics sintered in a constant magnetic field B = 0.02-1 T with a given C3 symmetry at 1200-1400 °C has improved physical and mechanical characteristics and more perfect crystalline forms of microstructures.
