ミリ波帯電磁波ならびにパルス大電流印加によるセラミックス焼結プロセス Ceramics Sintering Process by Millimeter-Wave Radiation and Pulsed High Current Supply
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 Al<SUB>2</SUB>O<SUB>3</SUB>+ZrO<SUB>2</SUB> composite and Si<SUB>3</SUB>N<SUB>4</SUB>, as well as of TiN+Cr<SUB>2</SUB>N 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.
