Abstract

The properties of ceramics obtained by sintering of compacts from ultrafine and microfine aluminum oxide powders in a constant magnetic field were studied. Aluminum oxide activation sintering in a constant magnetic field makes it possible to reduce the sintering temperature of ceramics while simultaneously improving its quality. It was found that the effect of the magnetic field is most pronounced when sintering compacts from micropowders. It was determined that the density, microhardness, and tensile strength significantly exceed the corresponding values established for ceramics obtained by sintering of compacts of ultrafine aluminum oxide in a magnetic field.
