## Abstract In this study, the compaction and sintering behavior of fine alumina powders of different particle sizes and the effect of matrix particle size on biaxial strength and fracture toughness of infused matrices were investigated. Three different alumina powders, InβCeram alumina, A16SG, and
Commercial alumina powder was densified by spark plasma sintering (SPS) at 1150 β’ C. During SPS processing, the effects of the heating rate were examined on microstructure and transparency. With decreasing heating rate, the grain size and the residual porosity decreased, while the transparency incre
