This study focuses on development of advance ceramic with improved toughness which can be used as armor material forpersonnel protection. Toughness is the characteristics that defines material resistance to fracture. Ceramics are important classof materials with combination of good strength, toughness and with stand multiple-striking. In this study, three differentsamples i.e. alumina, Zirconia toughened alumina (ZTA), and alumina incorporated with SiC (SiCA); hexagonal shapesamples were made by dry pressing and sintered at 1600 oC in argon atmosphere. Microstructural characterization: SEM andOptical microscopy demonstrated fine grain size distribution in matrix phase. BSE images confirmed the presence of ZrO2particles. High porosity of about 6.35% was observed in SiCA samples. EDX analysis confirms the composition. Mechanicalcharacterization showed improved toughness at the expense of hardness. SiCA samples showed maximum value of hardnesswhile ZTA showed maximum toughness of 4.6 MPa·m1/2. The obtained properties are comparable to other ceramic materialsprepared by different methods.
