Abstract
Research on ceramics sintering by milimeter-wave range microwaves is briefly reviewed in conjunction with that by pulsed high current supply. Unique features of mm-wave sintering are demonstrated in comparison with sintering by electrical furnaces as well as by 2.45 GHz radiation. Studies on mm-wave sinterig of Al2O3+ZrO2 composite and Si3N4, as well as of TiN+Cr2N composite, which has been conducted at JWRI, Osaka University, are described. Sintering mechanism of mm-wave radiation and pulsed high current supply is discussed based on the electromagnetic phenomena within the powder particles and grain boundaries.
