1 INTRODUCTION Alumina (α- Al2O3) is one of the representative ceramic materials used in critical structural components due to its superior hardness and strength-to-weight ratio.1-4 Processing of Al2O3 by a conventional pressureless consolidation method takes more than 10 hours above 1400°C to reach a high relative density.5 As the high temperature and long sintering time lead to significant grain coarsening, an alternative sintering technique is necessary to prepare dense specimens with...
